The HTML5 incarnation of DaisyBall opted for a general audience presentation. Choice of DaisyWorld or DaisyBall logic (2D or 3D world). Easy access controls for high level concepts, but you can still set advanced parameters. Easy to set albedos and number of daisy colors.

The topic of this website is programming. For my author site, I originally cloned from my programming portfolio site, cut, then extended for years, then recently migrated from Drupal 7 to Drupal 9.

Mandalar - Pattern Blocks is now on mobile! Mandalar is a port of Pattern Blocks to Android and iOS, using Adobe AIR - same source, all platforms. Cross-operable with the web version. Designs saved to the Art Gallery can be edited with either browser-based Pattern Blocks, or Mandalar for mobile.
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.

The scientific model is simple equilibration. I didn't develop the math on this one, only the interactive and graphics portrayal.
Demographics explores population growth pyramids, much like my earlier Human Demographics simulator, where you can change birth and death rate schedules. In this rendition, the user can set vital rates to match those of a different country. (E.g., how would India's population develop under US birthrates.) Countries: USA, China, Egypt, India, Italy, Mexico, and Nigeria.
Fractal Music Composer is a powerful music editor. Students build their own musical phrases out of notes from their choice of multiple keys and musical scales. Compositions are built from notes and phrases playing on assorted instruments. Fractal editing operations create self-similar sequences across different time and sound scales. Students can save MIDI output of their creations, which can play their music on almost any computer.
Click to listen to a sample composition made by applying fractal operations on two phrases from Pachelbel's Canon.
