Non-verbal IQ testing

Every once in a while even cpunks need a little respite from ranting, and some refreshing topic which hasn't been beaten to a painful ad-hominem-death a thousand times already... so here's the topic. What methods are there for doing non-verbal, cross-cultural IQ tests? Some obvious things come to mind, like geomtric analogy questions, but that would seem to favor people who have strong spatial or visual reasoning, which is only one aspect of overall intelligence. Any other options?
