Pattern Blocks are used in early math and just for fun. Great for drawing mandalas, tilings, and tesselations. Originally written as a toy for my daughter in 1998, this is my most popular app by a landslide. Latest version features full-browser resizing, better email, hundreds of backgrounds, and keystroke shortcuts. Now with Art Gallery for kid-safe sharing!

Mandalar is PatternBlocks for mobile! PatternBlocks is now released as a mobile app. See Mandalar. Still in Adobe Flex - all web/mobile platforms are cross-operable.

SimWatershed is loosely based on the real-life Esopus Creek watershed, part of the naturally-cleaned water supply of New York City. SimWatershed implements two online labs, for the Yale School of Forestry graduate course Science to Solutions: How Should We Manage Water.

In the "Biophysics" lab, students explore how water quality is affected by adjusting land use - suburban, agricultural, livestock, and forest. Then in the "Solutions" lab, buying land costs money and faces limits. Other social treatments are available at a price: best management practices, upgrading the local sewage treatment plant, raising prices, or building a city water treatment plant. Scenarios explore present and future, nitrogen and sediment.

NumBlox Freeplay is a cusinaire rods game. Cusinaire rods (number blocks) are used to teach early math. NumBlox features a simple, clean interface, with rotateable drag and drop blocks on a grid, and a play area that grows to fit your web browser area.

MathToybox is the new social home for my kids' games, featuring PatternBlocks Art Gallery, direct access to the Triaxle Scoreboard, and room to grow in a kid-friendly design.

Originally Flex3 / PHP, now rewritten in jQuery / PHP.

Vick Art Advisors manage corporate art selections. This brochure website showcases their work.

CrossPlan / Cross-Suite is a site for social integrated circuit block-level layout editing. I built database, intelligent integrated circuit editor, design history management, integrated instant messaging, and the whole Drupal site, for The Shearwater Group and Pinebush Technologies. This site is not public - please contact me if you need a demo. Alpha release only - the recession put this project on hold.

FlexSimpleStats tracks semantic usage statistics within my simulators - what users actually do with them. These days, one can use Google Analytics for this, but SimpleStats predates GA by years. The server side of SimpleStats is implemented in PHP and MySQL, called by client-side Java, Flash, or Flex. This tool browses and charts CourseWare historical usage data, back to January, 2004. Originally implemented in Flash, now in Flex.
