Overpriced, but interesting...
From the perspective of expecting to see total oddities, I got what I expected, but for the price ($20+), I don't think it was worth it. It had some interesting stuff, but nowhere near enough. There were some interesting little gag things like the "laser harp", and the thing that played with how your face looked, but overall there wasn't enough to justify the cost. Unless you're really bored, I wouldn't suggest wasting your time or money here...
