calc.org
I was an active participant in the not-so-small community of graphing calculator program writers a while back, and still occasionally participate within that community. One of the sites that predated my use of graphing calculators was calc.org. It had, however, suffered from neglect and was closed down. In 2005, a revival effort started, and I jumped at the chance to help out the community. I designed and built early concepts of the site, but the project fell through like the site, and now this is all that is left.
