I have an image in my head that they'll have so much fun doing volleyball. Or just plain passing paperballs around. Really cool and really good. I wish I could reach such height of story drawing like you!.
Hey, fun octopus facts! Octopuses can't see in color, but they are able to differentiate light by polarization. It also looks like stereoscopic 3D pictures wouldn't actually work for octopuses since the parts of their brains that process data from their optical nerves don't appear to share impressions like human brains do. Polarized 3D, like most of the 3D movies coming out these days would be even more confusing to the octopus, since they would see both of the interlaced lines separately and even pick up the circular polarization that's being reflected by the movie screen that the glasses normally filter out.
I did some experiments with split polarization goggles underwater and its super amazing how well fish scales stand out, so I imagine that's one of the reasons octopuses are so good at visual hunting.
