Bugfixed.
The classic spin the bottle game. Did not have a real bottle? Are you afraid to hurt you with a glass bottle? Good, you can use this and have fun with your friends.
The application also allows to change the background above which is spun the bottle, each background presents a different frictional force.
In addition to standard bottle spinning it is also possible to simulate the roll of a dice or a coin toss (heads or tails).
Have fun.
