Official Code Off: STAGE 2

2D Graphics

This is the second of three challenges. To complete this stage you must program a 2D graphical application that initializes a new 'Square' on the screen each time the user left-clicks. Each square will move at a constant speed in a random direction. Upon contacting a window border, the square will bounce off and continue in a new direction.

Each contestant has 24 hours to complete. Code must be posted in this thread by 4pm eastern tomorrow. This stage is slightly easier than the first, so I expect more than one legitimate entry!
