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.
