Fancy Frame
This is the project that convinced me that soldering is something I know how to do and can do, but is not something I really enjoy.
Unimatrix (Part 2)
It would allow me to make use of idle resources, use more efficient power, and consolidate everything into a single place. It also meant a ton of software work, re-configuring all of my existing services. Joy.
Canvas
Canvas started as four (and then, a few years later, six) separate lights, but they have since been rebuilt into a single light with one controller to run them all in sync. This allowed the effects to flow from one frame to another, which made for a neat look.
Panel Lights
I don't know what most people do when a major piece of electronics fails, but for someone like me, a big LCD display with backlights, speakers, panel, several diffusers, etc? It was whale fall.
Spaceship Lamp
The shape of the lamp was absolutely inspired by UFOs. Specifically the ones commonly blamed for cow abductions. This one has a much bigger dome at the top, presumably to hold more cows.
