just for a bit of fun at the mo. more on this later... (now little bit in PART2) + check it out on the new album by david burraston & russell haswell.
gravity/black hole-ish module, running a simulated physics. separate control voltage outputs from
asteroid-like ships xy position. 4 x gate toggles when ship passes corresponding screen
boundary. control voltage for ship rotation and thrust. each gravity blob has its own forcefield.
