Comment I used to work for a company that did this (Score 1) 122
Years back I worked for a company who did a very successful display at the Louisiana Children's Museum in New Orleans: http://www.bentmedia.com/case_studies/teamturtle.php
The computers were all touchscreen enabled and put into cabinets like kiosks, and they were scheduled to automatically restart if a crash was detected and relaunch the multimedia presentations. The exhibit itself was bright, colorful, and interactive.
I wasn't directly involved with the implementation of this project so I don't know all the details, but maybe from the photos in the case study you can get a sense of how it was set up. I remember it being a pretty big hit - and while I don't know the extent of any "unpleasant surprises" that are sure to occur with a project like this, when I visited the exhibit I recall everything working very smoothly.
