I think I have teased this already, so here it is:
Proudly presenting “ligra”, an open source projector/projection (LiGra – Light Graffiti) platform, allowing you to broadcast your messages, your logos, your artwork, whatever you need others to hear, to whoever sees it! :3

With ligra I wanted to explore image-projection and especially projections on the cheap, so I went to my local flea market and built a platform around old camera lenses. You can find two of them in the wild at

A gentleman named Paul Khoury approached me about getting a retro computer he'd acquired up and running. The computer is a Sun SPARCstation UPN (1997), a prototype for a super small desktop computer that preceded the Mac mini by about 6-7 years. Only about 20 were ever made. I was the designer on the project and had poured my soul into it, so I was proud to help him get it running. I dug out the schematics from storage and gave any advice I could remember and he got it powered on in a few days.
