To the left is a gear box of sorts.
  • Click and drag to make a gear.
  • The first gear moves on its own
  • Other gears move if they mesh with a moving gear
  • Click and drag a gear to reposition it
  • Drag a gear out of the box to remove it
  • The physics aren't perfect, but it's still fun

This is part of a continuing series of experiments to develop an interactive gear system. This "sketch" demonstrates collision detection between the gears. Here is my first sketch, which is less interactive and fakes the collision detection.
