I like the slot machine ad WebmasterWorld is showing for the Las Vegas conference. But it took me a while to figure it out the first time. When I look at it again I realize what is missing: the handle. A right hand side handle which pulls before the slots move would definitely do the trick. And while you are at it, do something about those thick black slot borders, they make the ad look a bit "plain"... Go for a more 3D like appearance in the slots.
In any case, the ad concept is brilliant given the location of the conference...
