Algodoo

a roller coaster, i visited alton towers yesterday and was just looking at the mechanics while i was waiting in the cue for air. w and s make the seats tilt up like on the real thing. the car has no built in drive power and just uses the lift and gravity for power
the lift took a long time to make but works extrmemly well
future features:
-more compact lift chain. ( you can use this in your roller coaster if u giv me credit.)
- a rollercoaster that doesnt use the bottom of the track and the top.
also lots of other new features:D
the tracks were cloned from the deadcoaster (credit to the maker:D) but rearanged in my own way
rate and comment nicely please
