Perhaps your pdf-viewer does not support javascript.
I use acroread version 9.3.2
Cheers, Peter
After short research I found out that most pdf readers don't support Java
Script (so do xpdf and sumatra). So, this is not really a portable solution.

Any hints for achieving the same result in a portable way without Java
Script appreciated.

I think that a luatex solution should be easy (for Hans, hint hint).

Collect everything on a page, and do some attribute magic to reveal it one by one (or change colors, etc).

I was thinking the same thing (including the Hans, hint hint bit :))

By hooking into the output routine using attributes, there would be
no problems with environments and/or macro expansion, and even better,
everything has to be typeset only once.

Best wishes,
