correcting noisy spatial scans from MadMapper
I’ve been using MadMapper for a while now, and it certainly saves a lot of time and effort compared to my home-brew solution that I’d been using before. One of the amazing things that MadMapper can do is what is known as “spatial scanning.” The result of a scan usually looks something like this: It [...]
in which I go insane, make quarter scale NES cartridges by hand
I’ve recently been playing with a local band called Emulator. We do covers of old Nintendo game music and I play the projector (meaning I do all the projected video effects). The music is great, and I get to try out all sorts of fun projection mapping ideas. There will probably be a blog post [...]

I’ve used the max7219 to do a one-bit 8×8 matrix, but the idea of being able to drive full color video is an intriguing challenge. After a freelance job inquiry came in regarding RGB LEDs driven by an Arduino, [...]

In addition to providing projection mapping for “Capital Capitals,” I worked with Bryan Markovitz to create an installation piece based on Gertrude Stein’s novel “The [...]
Rapunzel, Rapunzel, let down your.. verlet physics simulation?

The set features a large projection screen for scene-setting rather than having physical set pieces (the play is a pop-rock musical and most of the set resembles a stadium concert stage). Among the challenges of [...]
