Nice. How did you do those?

Both were generated by one of our VME module arbitrary waveform
generators. The "Highland Hills" were made by one of my guys who
scanned and vectorized our logo somehow.

I did the spiral as a built-in-self-test routine. It's just a few
lines of 68K assembly code, basically a pair of coupled integrators.

Good old fashioned game of NIBBLES.BAS.

(Which, in turn, means he must've written an 8051 emulator, thereby running
his 8051 BASIC on the PIC directly!...)
