===
This directory contains a number of simple hacks come tests come
examples come clutter demos.
There are:
o test
Lots of randomness. Scratchpad to test new features.
o test.py
Like above but more randomness in python.
o super-oh
Spinning OH logos. Click to dissapear.
o video-player.
Simple fullscreen video player.
- Move mouse to see controls.
- Hit q or Esc to exit, p to toggle pause state.
- Has some useless cheesy effects built in.
- Hit e to flip the video.
o video-cube.
Pure evil. A nasty hack to do a video cube with clutter.
Could be done much nicer.
Also see http://svn.o-hand.com/repos/misc/trunk/opt for a simple
clutter based presentation program.
