A hobbyist classic

I had an old Radioshack project box laying around for a couple of years, until it's lack of use annoyed me to the point of motivation. The laserspirograph is an ancient classic among electronic hobbyists, dating back to at least the early 1990s with the advent of cheap laserpointers. It's a fun, easy project, and with how amazing the esp8266 turned out to be, I decided to take a shot at modernizing the concept a bit.

In ye olde days these things were usually equipped with a myriad of switches, potentiometers and the like, but I wanted to be able to control mine remotely and reliably store the patterns that I liked.
