EDIT:
So I guess I found those two that weren't listed before:
Spoiler
Devo (round red hat in the Tardis)
SebastiAn (Ross Ross Ross cover on the Tardis)
Action Jackson got Devo waaaay back in Reply #2.
But you can have Sebastian Actually maybe you can't. Others here think it's the Human League. I'm not sure which it is now.
EDIT bis:
And the calendar now points to April 14th, another reference to Aphex Twin
Good spot. The Blue Monday date is strewn on the floor, rather disrespectfully now.

EDIT ter:
deadmau5 (there's a dead mouse)
What do Bis and Ter mean? [EDIT: oh it seems to be a Latin-derived thing that French people use.]
Oh also, we have Herbie Hancock's mechanical Rockit legs on the left. But could the mechanical arm on the right be a reference to the Chems' Believe?
DON'T. LOOK. DOWN.
