An engineering student friend of mine, Robin Marks, made this recycling when doing a school project. It is now in his parents kitchen, and doubles as a work surface.
What you do is revolve the dark green circular cover until the smaller circle is above one of the 4 internal recycle bins, then drop the recycling in. So it is tidy, sorted by type and looks good too.
It is really well made, with the the darker green circular piece of MDF rotating on ball bearings which lie in a groove routered into the top of the cube. Awesome.
