So you think you know your design jargon? Check out this neat Flash game I found on the web:
Find the 25 Design Terms
After you enter the game you're confronted by an illustration of a spooky street corner at night. See the dead guy in the gutter with a pool of blood? Click on the blood and the screen highlights it, shows a definition of Bleed ("An element that extends beyond the edge of the page") and fills in #1 of the 25 design terms contained in the illustration.
If you can find the other 24 within the time limit you can win a limited edition poster of the illustration, otherwise you can always purchase one. It took me four tries before I was able to locate and click all 25 representations of design and prepress terms within the time limit.
