LoopdeLoop is an animation challenge. Each month, animators from around the world create looping animations based on a given topic and upload them to http://www.loopdeloop.org. On the last Tuesday of the month all of the posted loops are compiled and screened to a live audience at Loop in Melbourne, Australia. During the screening a winner is declared, who enters the hall of fame and has their loop featured throughout the following month.
The last challenge spanned two months, Sep/Oct and the theme was “Hallucinations”. Below are the winners and some of the more interesting entries (some are animated gifs.
