I created this new forum upon realizing this is an area that probably deserves its own home. Specifically, I was flipping around the TV in a hospital waiting room, and saw a segment on Animal Planet where an octopus was playing with giant lego blocks. As many of us know, our own Carol invented this interaction model several years ago with her bimac Ink, and I was happy and proud to see it emulated on that program. I came to post about it, and found that we really could use a dedicated forum for this purpose. So here it is -- enjoy! I'll move some relevant posts from the past into this forum so that our content remains organized.
