Solution to the make up four puzzle

A virtual star to Mr. B. on solving the puzzle. Remember, the idea is to move only one stick to make the equation correct:

Starting postions: | + || + ||| = 4
Solution: | + | + | + | = 4
(move one of || to make a "+" with the middle stick in |||)

I have made a little Flash animation to demonstrate it, but I can't figure out how to upload this to Blogger. If you know, please advise.

Elias.
