Peaceful stimuli for a Friday afternoon

Two bits that are pretty neat:

• A video montage of images and short clips that make neat visual or intellectual pairings. I don't want to spoil it for you by saying more...
  (via dooce)
  
• Similar but different, out-of-phase pendulums make a constantly varying and remarkably beautiful set of patterns. Almost poetic.

Have a good weekend, all!
