Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from application logic. This implies that PHP code is application logic, and is separated from the presentation. The Smarty design was largely driven by these goals: clean separation of presentation from application code; a PHP backend and Smarty template frontend; compliment PHP, not replace it; fast development/deployment for programmers and designers; quick and easy to maintain; a syntax that is easy to understand, with no PHP knowledge required; flexibility for custom development; and security (insulation from PHP).

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.
