Some programs that I maintain

All include C or Java (some for Android) source code and now some in JavaScript which are covered by a BSD copyright. All Java programs (now Java 8) can be copied (or rebuilt) and run as an application. I figure I wrote about 95% of the non xlock stuff (though I did build upon some great ideas).

Latest toy (circa 2017) from Tom Miller is a coasting unicycle. Hard and scary, still just learning riding uphill on it. Previous toy (circa 2015) is an adjustable reverse steering handle bar attachment. Attached just fine to my old bike. Learning to ride a bike all over again.
