I saw impress.js, a really cool CSS3 transformation-based presentation Javascript library on Hacker News yesterday. The demo is flashy - similar to Prezi but without Flash, plus new 3D effects. The only downside compared to an established browser slideshow library such as S6 was that my Logitech presentation pointer didn't work for advancing and reversing the slides.
After a little digging, I found out that presentation pointers emulate page up/down key strokes. So I forked the impress.js library, updated the code, and issued a pull request to add the presentation pointer capability. Thanks to Bartek's quick response, the pull request was merged and closed just a few hours later. So now presentation pointers work great with impress.js.
