Bump Glass

This shader simulated the distortion that you would get looking through uneven glass - that rolling, rippling effect that you see in old mirrors.

You can control the intensity and the scale of the rippling. The the effect can be animated for a rolling, boiling look.

OPTIONS:

• Bumpiness
  The 'size' of the bumps in the glass. A higher number = more bumps = smaller bumps.
• Intensity
  The height of the bumps
• Speed
  The animation speed (for rippling glass). This is currently experimental
