How it works
This generates VGA output for a pseudo-3D sine wave ribbon animation and some simple music. It uses the VGA and audio PMODs listed below.

How to test
Set the input clock for 25.175MHz. The Pico/RP2040 can output 25.177MHz on GPOUT0 with a 125MHz main clock and a divider of 4 [integer part] and 247 [fractional part]. This worked on my TV.
Reset, and enjoy. :)
