more distributing random dots in disks
trying to distribute random dots on the unit disk so that their projection onto any line is uniform.



Spangled ! (iOS)  2012-2013
A gentle, Ever-Changing Musical And Visual Patterns, and ultra-simple interaction make this app a sure winner.



YourBase (iOS)  2013
iOS-evolution of 'arbitrary base conversion in javascript', below.
Primarily written as an iOS exercise in custom keyboards, multi-view controllers, etc.




Inspiraled (javascript)  201112
fun with spirals
spiral particle systems on canvas w/ javascript.
suitable for mobile


PixelFilter (javascript)  201112
simple javascript + canvas pixel filter
does a simple blur and color-lookup for the Obama Poster effect.
in HTML5-compliant browsers, can use a local file.
suitable for mobile


HandyRand (javascript)  201011
a simple randum number generator
to assist with operant conditioning, variable-ratio schedule, behavior analysis, and behavioral modification.
thanks to mike for the call-out !
suitable for mobile


Curves (javascript)  201010
a nifty parametric curve plotter with:
  • arbitrary function input
  • time-variance
  • and
  • interactive associated curves such as The Pedal and The Normals
    •

    Magic Donut (iOS)  2009-2011
    One of my earliest forays into iOS programming, and a continuation of my obsession with toroids.
