best suggestion i've read is odd-one-out:

	Which of the odd one out in the following list:
              red, blue, green, purple, jupiter

zillions of alternatives:

	      car, train, bus, plane, apple
	      a, b, c, d, e, 9
	      tall, short, fat, skinny, kangaroo
	      noun, adjective, verb, rose

and so on. 

these can still be solved by the $0.02/hr CAPTCHA farmers, but they do
work for blind users and they are not ugly to look at. they also require
a small amount of intelligence, which is no bad thing :)
