pleasantly surprised by their approach; that they really did say: "Here's some amazing pre-release hardware" -- which always gets me especially excited -- "see what you can make with this". We used 4D immersive particle simulation via a mixture of processors from within the Ultrabooks and a series of 3D mirrors to create the three installations. PH: The first time we went through a kind of open-source conversation with a big company was with Coca-Cola. We spent two weeks talking to them about how and why we should open source the project, and after the project was finished, we took the codes to build software for children on the autistic spectrum -- then they saw that through open sourcing, the project had life, and, cynically I guess, they could capitalise on that. It's that contradiction -- if you give something away, you protect it a lot more. The concern from Coca-Cola was that another brand could take the code and use it, and we said, "If they did do that, that would be the greatest PR ever." Hellicar & Lewis' most recent project was for the launch of the next generation of Intel processors. 'Triptych' harnessed the processing power from a series of ultrabooks to a create a trio of interactive installations CA: How is the work going with the Somantics software for children on the autistic spectrum? PH: We've been working with our collaborator Dr. Wendy Keay Bright in Cardiff for the last couple of years, and it has
