Also bought a Matrix Portal and have had a lot of fun with it! Dabbled in writing a raytracer for it, but I don’t know enough about ARM nor C++ to optimize it for decent frame rates. Now the thing runs a newton’s cradle simulator using Box2D, and that’s been a fun desk toy.

Neat. I'd love to see what that looks like (raytracer or cradle). Found an old Hack a Day from 2014 (https://hackaday.com/2014/11/25/ray-tracing-on-an-arduino/ https://hackaday.com/2014/11/25/ray-tracing-on-an-arduino/) where someone is raytracing on a 16Mhz micro. Should be faster on the 120Mhz portal, but it took almost 3 days :P
