Color Wheel: This project was an attempt to do automatic color calculations via PHP. I am actually performing HSL calculations in a polar coordinate system, and then extracting the data into an RGB grid. This could be handy for determining font colors given the color of an element. Or testing the visibility of a font with a given background. But primarily it has just ben an experimental work in PHP and mathmatic color calculations.
User Information: This project has been very useful for debugging browser related problems to be able to determine exactly what browser or information could be causing a problem.
ASCII Table: I find I always have to look up the ascii chart for some reason, and find many of the sites to be too cumbersome (just images) or full of ads. So I made my own. (I am currently importing this from my old site.)
Text2Audio: This is a linux shell script that can convert almost any source of text into audio files to be heard.
