Ever go to the park to play just one game of 500, and no one's there? Then this is the game for you! The thrower (at the very right of the 500 court) will call out "Dead ??? Alive ??? and you try to catch it using the arrow keys before the other player does using WASD. If you catch it before it touches the ground it is 'Alive', otherwise it's 'Dead'.
To make the ball bounce, I took the equation for the damped sine wave: e^-i*cos 360i I squared the i in the cos function in order to speed up the frequency over time. Then, I took the absolute value, multiplied by 75, and added 50 to get ball size right.
