It would take me a long time to really answer this because I’d have to really think of all of the things I’ve seen, but I did recently see an short animation that was quite morbid and definitely what most people would consider “weird,” I love it, though. Here.
Each year here at Texas A&M the students from the Visualization deparment put on a show called “Vis-A_Gogo” for the public that highlights the work that they have done over they year. It always has some of the most cutting edge shorts and animations that you will see anywhere.
