KeyJnote is a program that displays presentation slides. But unlike OpenOffice.org Impress or other similar applications, it does so with style. Smooth alpha-blended slide transitions are provided for the sake of eye candy, but in addition to this, KeyJnote offers some unique tools that are really useful for presentations.
It didn’t work on my Windows laptop, but it certainly looks like a bright idea to me! Note that the “J” in the name is a bit misleading – KeyJnote is not implemented in Java but in Python ;)
