Among the many groovy aspects of PTSOS is the sharing among participants. The veterans up front have seen many things, but we haven't seen it all.
While discussing the Bell Labs wave machine, one of the participants at yesterday's PTSOS2 mentioned a Gummi Bear wave machine made with bamboo skewers and tape.
Here's a link to a video of the device. In the UK, they have Jelly Babies rather than Gummi Bears. (They also have G-clamps. Honestly, isn't that a better name than C-clamps?)
Looks like a winner to me!
I'm thinking... Dots or Crows might be the way to go on this (in the states).
