We used something similar in 2008 at CeBIT (which was the biggest IT trade show in Germany at the time). A publishing house for IT magazines set up a side area for minibooths and gave them out to a dozen open-source projects. I was there with a bunch others to represent KDE. We only had a few posters and stickers, nothing fancy, so we had to make our booth flashy somehow. My friend quickly hacked together something with a similar input simulation tool that opened applications from the start menu, flipped through directories in Dolphin, and such, and set it up to run in a loop. It sure did help us catch people's attention.

> I have started using xdotool [1] to create bash scripts that send mouse clicks and keystrokes to apps. Interleaving calls to xdotool with the "sleep" command [2] produce a convincing effect.

Can you share some of these scripts?

Love this one.

For the clicking sound you could add something like the below command on each click.

'aplay click.wav'

that's really cool, thanks for sharing
