ActionScript 3

I built these interactives as part of a feasibility study for a client, for using Adobe Edge instead of Flash to build simple games for eLearning. Adobe Edge is an authoring tool which outputs cross-platform HTML5 with animated div tags. The question was whether the tool could build good-enough interactives, as quickly as they could be made in Flash, and truly operable on both desktop and mobile browsers. This was successful - Adobe Edge was good enough, and actually faster than Flash for development. Targeting more platforms is slower for testing, of course.

The interactive itself is a throw-away, obfuscated a bit at the client's request.

The DiffEQPlotter explores graphical solutions to differential equation systems. Nine equation system families are provided - some simple algebraic systems, some ecology models, and some limit cycles. Each can be tuned by setting constants. Paired time plot and phase plot show the behavior of the system (trajectory) from any selected starting point. The phase plot also shows the "nullclines" (where the derivative of each equation is zero), and a vector field showing the tendency of the system across a grid over the plane.

Though not "fractals" software, it was developed for the same mathematics professor, Michael Frame of Yale University.

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

New version! NumBlox 2.0 features pencil, eraser, choice of grid style, stacking blocks, and scrollable edit area. NumBlox 2.1 adds 3 choices of block color scheme.

Now for mobile! NumBlox is now available for iOS and Android, too! Mobile versions feature native sharing to Facebook, Twitter, and Email. Sharing can be disabled for young children. Now also available for NOOK HD^TM and NOOK HD+^TM by Barnes & Noble.

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.
