AIDS (AJAX Image Dump System) is a simple, yet powerful AJAX-based image host system. It's geared toward forum usage, and it generates bb-code for cutting and pasting into forums that support bb-code. It lets people create user accounts to keep track of their pictures, reaccess them later to view stats, delete them, or simply copy the bb-code again.
Asymptopia Crossword Builder (Math/Text) is an application that runs in any modern Web browser, but does not require an Internet connection (if it is installed locally). The application was designed to allow teachers to quickly produce well-designed, challenging activities. The application features a configuration panel where the user can either enter their own word-hint pairs, or generate math-crossword problems via a single button. The math functionality generates word:hint pairs like: "four:7/x-3/8=11/8", where the hint corresponds to the problem, and the student would write the letters "four" in the corresponding boxes of the puzzle.
