My prototype spawn engine.

Uses multiple circles to simulate expansion, this create more torque compared to current single circle spawn engines.
Especially in high load application as spawning of circles contines to happen, forcing the piston down.
Throttling made difficult to due low effects on rpm by changing density of circles.
"Exhaust stroke" occurs by changing all cicles' timetolive variable to 0.

Pros:
High torque relative to size, and displacement.
Use of easily controlled numerical values to configure:
spawing of cirlces
circle live time
Cons:
No/Limited throttle control through conventional means.
High vibration when circle density is relativly high.


Controls:
up arrow = increase circle density
down arrow = decreased circle density
i = start engine
