Help with my burning desire to build something!!!

Ok, well recently i've been getting tired of playing my xbox all day and feel as if I need to be more productive with my free time. Three things have interested me a lot are; lasers, speakers/audio, and LED's. I really want to so something including one, if not two of the three interests. I've never soldered but im defiantly going to learn how. The biggest project i've done so far would probably installing lights in my xbox along with cutting out a two windows too see them.

I need ideas. Summer is just around the corner and will have plentiful free time. Any idea I will consider because im always up to learning something new.

Any ideas will be GREATLY appreciated!!

You say you're into speakers... Building my own was a lot of fun, and I'd definitely suggest that. Check out HTGuide or AVSForum for tutorials and lots of completed speakers.
