All living organisms are composed of cells, and cells are fluid-filled spaces surrounded by an envelope of little material- cell membrane. Frei Otto described this kind of structure as pneus.

From first order,  peripheral conditions or the packing configuration spatially give rise to specific shapes we see on the second  and third order.

This applies to most biological instances.  On a larger scale, the formation of beehives is a translated example of the different orders of ‘pneu’.

Interested to see the impact of lattice configuration on the forms, I moved on to digital physics simulation with Kangaroo 2 (based on a script by David Stasiuk). The key parameters involved for each lattice configuration are:

Inflation pressure in spheres
Collision force between the spheres
Collision force of spheres and bounding box
Surface tension of spheres


Physical exploration is also done to understand pneumatic behaviors and their parameters.

This followed by 3D pneumatic space packing. Spheres in different lattice configuration is inflated, and then taken apart to examine the deformation within. This process can be thought of as the growing process of seeds or pips in fruits such as pomegranates and citrus under hydrostatic pressure within its skin; and dissections of these fruits.

As the spheres take the peripheral conditions, the middles ones which are surrounded by spheres transformed into Rhombic dodecahedron, Trapezoid Rhombic dodecahedron and diamond respectively in Hex Grid, FCC Grid,  and Square Grid. The spheres at the boundary take the shape of the bounding box hence they are more fully inflated(there are more spaces in between spheres and bounding box for expansion).


Physical experimentation has been done on inflatables structures. The following shows some of the outcome on my own and during an Air workshop in conjunction with Playweek led by Will Mclean and Laylac Shahed.

To summarize, pneumatic structures are forms wholly or mainly stabalised by either
– Pressurised difference in gas. Eg. Air structure or aerated foam structures
– liquid/hydrostatic pressure. Eg. Plant cells
– Forces between materials in bulk. Eg. Beehive, Fruits seeds/pips

There is a distinct quality of unpredictability and playfulness that pneumatic structures could offer. The jiggly nature of inflatables, the unpredictability resulted from deformation by compression and its lightweightness are intriguing. I will call them as pneumatic behaviour. I will continually explore what pneumatic materials and assembly of them could offer spatially in Brief 02. Digital simulations proved to be helpful in expressing the dynamic behaviours of pneumatic structures too, which I intend to continue.


An exploration of the simplest Hyperbolic Paraboloidic ‘saddle’ form has lead to the development of a modular system that combines the principles of the hypar (Hyperbolic Paraboloid) and elastic potential energy.

A hyperbolic paraboloid is an infinite doubly ruled surface in three dimensions with hyperbolic and parabolic cross-sections. It can be parametrized using the following equations:

Mathematical:   z = x2 – yor  x = y z

Parametric:   x(u,v)=u   y(u,v)=v   z(u,v)=uv

The physical manifestation of the above equations can be achieved by constructing a square and forcing the surface area to minimalise by introducing cross bracing that has shorter lengths than the  square edges.


A particular square hypar defined by b = n * √2 (b=boundary, n=initial geometry or ‘cross bracing’) thus constricting the four points to the corners of a cube leads to interesting tessellations in three dimensions.


Using a simple elastic lashing system to construct a hypar module binds all intersections together whilst allowing rotational movement. The rotational movement at any given intersection is proportionally distributed to all others. This combined with the elasticity of the joints means that the module has elastic potential energy (spring-like properties) therefore an array of many modules can adopt the same elastic properties.


The system can be scaled, shaped, locked and adapted to suit programmatic requirements.



Narrative | ‘Orbit’, an aluminium tube pavilion stands as a playful take on the orbit of our solar system. A kinetic, inhabitable architectural structure that orbits around itself revealing a central, occupiable space that acts as a ‘center of the universe’  location within which the occupier will experience the rest of the world rotate around them.

Occupiers act as planets orbiting around one another, taking in the beautiful surroundings as each hammock level gently rotates as if it is floating, free from visible connections below, In order to reach these relaxing levels, the occupiers must scale its lightweight structure eventually reaching the central ‘ritualistic’ epicenter.

Physical Description | Orbit stands as a playfully abstract vision of the universes orbit around the sun. Visually the structure is very simple. A series of single recursively scaled down forms provide both the frame work in which to house multiple levels of hammock space to relax whilst also offering a highly structural climbing frame that is scaled in order to reach its epicentre.  It stands tall amongst its neighbours as a combination of both inhabitable architecture and a visually striking art piece.

The structure is composed of multiple interlocking aluminium tubes of varying diameter that hang from a single point supported by the main outer structural framework.  Within the opening at the bottom of each frame is space for hammock netting to be fitted to the aluminium tubing providing an inhabitable space to relax on.

The inset neon LED lighting on the inside of the aluminium tube frame enhances the proposals visual impact at night, illuminating to be seen from near and afar.

Interactivity | There are multiple levels for potential seating, each incorporating a hammock like mesh suspended between the aluminium structure. This provides a comfortable place to relax whilst the structure gently rotates about its axis. As with most exciting Burning Man installations, this structure is climbable with the final point to reach being the central frame large enough for one person to sit in whilst the rest of the structure rotates around them.

Near Unison, my project exploring harmonographic traces is currently being shown at Kinetica Art Fair. The exhibition is in Ambika P3, the exhibition space attached to the University of Westminster on Marylebone Road. For more information on the exhibition, and details about tickets and opening times please visit the Kinetica Art Fair website.

Kinetica Art Fair - Near Unison

The exhibit features a prototype of the interactive harmonograph swings that could form part of the larger installation proposed for Burning Man Festival, along with casts of the harmonographic traces left in sand, and photographic work documenting the process.

“The 5th Kinetica Art Fair returns February 28th – March 3rd 2013 at Ambika P3, as one of London’s annual landmark art exhibitions and a permanent fixture in the Art Fair calendar, renowned as the UK’s only art fair dedicated to kinetic, robotic, sound, light, time-based and new media art.

Kinetica is hosting the work of over 45 galleries and art organisations nationally and internationally, with representatives from UK, France, Russia, USA, Poland, Holland, Spain, Italy, Hungary, Indonesia and Japan, collectively showing over 400 works of art.

A huge interactive light sculpture from Dutch artist Titia Ex will greet visitors as they enter the impressive Ambika P3 venue, and giant 3D sculptures from Holotronica will hover above the main space of the Fair. Other highlights include an exoskeleton hybrid of mananimal-machine by Christiann Zwanniken; a giant three dimensional zoetrope by Greg Barsamian; and a life-size ‘Galloping Horse’ made of light by Remi Brun”

Kinetica Art Fair Press Release

Very inspiring conference today at the Building Centre.
The conference runs for 3 days (21st until 23rd of February). It brings together the work of architects, engineers, manufacturers, product designers, academics and artists to explore the importance of prototypes in the delivery of high quality contemporary design. Placing a particular emphasis on research and experimentation. Prototyping Architecture forms a bridge between architecture, engineering and art, with exhibits that are inventive, purposeful and beautiful.

Some highlights of today’s talks:
