CRT Monitors... bulky old things that take up space in the spare room and generally sit there for years fulfilling no other purpose than a dust gathering device.
I was just clearing out my spare room today and there was "old faithful" sat there for years, so I got thinking.... After a quick search on google I found 2 pretty cool uses for old CRT housings.
1) The CRT fish tank.
Oh yes.. how cool would this look on your desk next to your computer.
2) The CRT pet hutch (Can't tell whether it's a hamster or a small rabbit :P)
Well, no where near as cool as the fish tank, but still a good use of something with no real other purpous.
