A one-way base converter. I can convert from base 2 to base 16 and a number 2 to 99999. To get an exact number, use left and right to change the number by 1 and up and down to change the number by 10. Press space to convert the number. It isn't very fast for high numbers. Hope you like it! Here is the reverse: http://scratch.mit.edu/projects/Daedskin/702069
