Andy Lomas: Aggregation, Flow

Computer graphics; simulation of natural processes of growth in a computer environment
Artefact: digital print,
Edition: variable, 2005.


The Aggregation series simulates emergence and growth of natural organic shapes in a computer environment controlled by an algorithm. It started out with love for coding in the free time of its creator, the mathematician Andy Lomas. Intrigued by an algorithm (aggregation with limited diffusion) used for the Matrix movie, where he was working, Lomas developed it so that it generates a simulation of growth with unpredictable results. It uses one ‘seed’ and one ‘walker’ circling around it and thus creates complex structures emerging from the invisible. The graphics consist of approximately 50 million particles and are not a result of a concluded process. Rather they reflect its creator’s aesthetic choices when observing the visible processes of aggregation in time.


Whereas the images from the Aggregation series directly show the deposited structures themselves, the images in the Flow series illustrate the other side of the same processes: the paths followed by particles before they deposit. They can be seen as the natural duals of the Aggregation images. They are composed of the layered trajectories followed by millions of particles as they flow in fields of forces. Each individual trajectory is essentially an independent random process, with the trail terminating when it reaches a deposition zone. Collectively, however, the paths combine to form delicate complex shapes of filigree and shadow in the areas of negative space that the paths do not reach. Over time, as particles deposit they create a growing region that future particles will not be able to enter. Subtle shadow-like structures form in the areas that trails no longer reach, reflecting the growth of the termination zone.


Andy Lomas is is a computational artist, mathematician and Emmy award winning supervisor of computer generated effects. His art praxis exists at the boundary between art and science and explores how complex sculptural forms can be created emergently by simulating growth processes. He is currently based in London, developing his art practice as well as working as a Lecturer in Creative Computing in at Goldsmiths, University of London.

Museum of Transitory Art

MoTA –

Museum of Transitory Art

MoTA is a multidisciplinary platform dedicated to advancing the research, production and presentation of transitory, experimental, and live art forms.

MoTA is a museum without a permanent collection or a fixed space. Instead, its programs are realised in different locations and contexts in temporary physical and virtual spaces.

MoTA organizes and supports transitory art in the form of continuous events, exhibitions and educational programs both locally and internationally. As its name indicates, MoTA examines what a museum can be today and in the future.

MoTA is in constant search for the new, the uncertain, and the undefined.

MoTA works on several continuous programmes & projects. We run MoTA Point – a Space for Art & Ideas, we curate and produce the annual SONICA Festival, in addition to regular music programmes such as SONICA Series and SONICA Classics.

Within the years of running our residency programme, we’ve established T.R.I.B.E. – a network of residency spaces in the Balkans & Eastern Europe.

We’ve also initiated the research and archive platforms and Mediateque MoTA & Tomaž Brate. Our educational programmes serve a broader audience with ongoing workshops, talks, symposia, and internships.
