Clockwork

Effects

 * Tears from the left eye will be "springs," which will bounce off walls and enemies similar to Rubber Cement.
 * Tears from the right eye will be "gears," which will deal 1.2x Isaac's damage
 * Items that increase the amount of tears Isaac fires (20/20, inner eye, etc.) work incredibly well with this item.

Trivia

 * Most clockwork systems have a series of complex integrated gears, but very few have springs in them.
