For those who don't know: Semester Opening ( http://semester-opening.de/ ) is a big party organized by the computer science students council of the TU Kaiserslautern ( http://www.fachschaft.cs.uni-kl.de/ ) at the beginning of every summer semester.
A month before the party z0ttel and I have been approached by the organisation team to add some special effects to the big poster, which was going to be put up at the Mensa. The theme of this years posters and flyers was space and so they wanted sparkling stars on their poster. Of course we could have just gone to ebay and ordered some led powered blinkenthingies to clue at the poster, but where is the fun in this ?
