I did a gig with Ameet Hindocha, aka Ambigraph, last summer and we ended up collaborating on an audio visual alt. soundtrack to Dune. I was so impressed with his geometric designs I asked him to do me a commission based on a complex pattern we both chose. Here are some work-in-progress shots and the final thing, all hand drawn, no computer was used, just pen, pencil and ruler. See more of his work here
