Mensa makes the IQ test using only graphics. There is 3 figures and you have to choose what is the fourth one from 6 (IIRC) choices. I haven't made official Mensa test (I made home test just for fun), but here is a link to one which tries to be like it. It is finnish, but if you are intelligent enough, you will figure out how to make it
There is 40 minutes time and you need to have flash on your browser in order to make it. When you follow the link, the test starts immediately.
