Na na, na na na na na na na na Katamari Damacy desk organiser. All you need is multi-coloured clay, sandpaper, a plastic ball, some glue, some plaster and some common household tools, and you've got an organiser ball the King of All Cosmos would be proud of. (Or not, he's kind of a jerk.)
Once you've got enough holes for your pens and pencils, use the leftover clay to make random miniature household items to stick on the outside of the ball. Bonus points if those items have an '80s Japanesey feel.
