Remember the Leonardo? Well, TreeHugger has a great compilation post about a bunch of other novel bike storage solutions:
The cute and curious Cycloc is essentially a plastic bucket that has two opposing “lips” that use your bicycle’s own weight to hold it in place. The void in the middle of the Cycloc keeps your gloves, pants clips, etc, close to hand, while holes in the cylinder allow you to fix a cable lock as well. 
Got lots of bikes? Something like the Cyclepod might be what you need. It provides eight secure spaces for parking your bikes, storing the bikes upright, and the front wheel and frame can both be locked in place. More good news: Cyclepod is made from 95% recycled aluminum.
