Here are some of my apps/examples. Click on any picture to see it full-size; titles link to live apps.

Note: I used to have limited versions of my apps on this site to prevent the potential for code-injection attacks/abuse, but I've since removed those safety restrictions: that means only use permalinks you made yourself or by someone you trust. Apps require recent versions of Chrome, Firefox, or Safari.

Teaching Examples

Screenshots I've taken from my collection of 150+ examples. Some of those screenshots are similar to the ones already shown above, so I've cut those out.

I've moved these pics to their own page, since this page is already too picture-heavy.
