Astronauts Playing Real World Katamari Damacy In SpaceS

I saw this picture yesterday and I just couldn't tell what the hell it was. So I read the caption and it left me even more puzzled:

STS-125 astronaut Andrew Feustel selects his next tool to use while participating in the first of five scheduled spacewalks to perform final hands-on servicing of the Hubble Space Telescope. Feustel and veteran astronaut John Grunsfeld (out of frame) are scheduled to participate in three of those spacewalks.

Tools? What tools? Can you see any tools in there? I have tried to decipher what tools are those and I just can't identify any single one of them.

Sure, I wasn't expecting a bunch of Allen keys and Torx screwdrivers to fix the Hubble, but these things look like fake devices from a B-series sci-fi movie. And now that we are at it, can somebody explain to me how can they make any sense of that big mess? Apparently, astronauts just tie their stuff in big balls of junk. Seriously, these guys are amazing. [NASA]
