Beary Bear

/*Originally created in late 2012 (https://www.openprocessing.org/sketch/84094) as a Processing porting of Robert Hodgin (http://roberthodgin.com/)'s

particle engine example in Cinder Introduction (https://libcinder.org/docs/guides/tour/hello_cinder.html).

Since the old sketch is archived and doesn't work on browsers no more, this updated version is uploaded. I also did some minor revision, inspired by

JaredCounts (https://www.openprocessing.org/user/3044)'s dough (https://www.openprocessing.org/sketch/65193).*/
