Guess the red value in a the flashing square. The green and blue are random but the red is constant. Type a value between 0 and 255, with 0 being no red at all and 255 being 100% red. Then press the space bar to get your score. The lower the number the better, with 0 being a perfect score.

Type the letter that appears on the screen! How many can you get in 30 seconds? Post your score in the comments. Refresh the page to restart the game. Hat tip to Kyle McDonald - I'd never used the textFont(createFont("",)) before. (contest wise this assumes that textFont(createFont does not violate the rules.)
