Poor Man's Key Hanger

Leaving a bunch of keys all scattered around the table bothers me and I just decided to look for some key hangers to put the poor fellas where they belong. The problem was i always forget to buy them until i got fed up so I just put together a few pieces of LEGO Technic plus some good quality double-sided tape to create my own version of key hanger, and Viola !

Another advantage for using LEGO to make key hangers was saving money on buying new ones :P

Can you think of something else to do with your LEGO ? ( preferably something useful of course. )
