Well. not a lot, but what I did find was kinda kitschy and cool.
There's a mini Rubik's Cube that bunnylogic turned into a pendant (bonus -- it's already solved!):

Or how about mini Rubik's Cube earrings from tinyminds (I love the checkerboard patterns!):

There's a Rubik's Cube felt plushie from kittymiaowwow (no hard plastic corners here!):

Or decorate your space with a Rubik's Cube decal from vinylwalldesign:

Whatever you choose, you'll be honoring the 80's in your own way! Just please, no parachute pants and Flock of Seagulls hair-dos. Some things should be left in the past.
