Ways to improve vocab? programs/activities! 10 pts!!?

Hi, I am looking for a program or activity to increase my vocab, preferably something other then sitting with a list of words and their definitions. (That's what I've been doing, and it just feels tedious and unproductive.) I was hoping there was an interactive site that had some kind of sound and image... but would appreciate any suggestions! I am also studying for the SAT's, so anything that's specific to that would be fine as well (but it doesnt need to be). Thanks!!
