When I was in Japan, I met a guy that made motion graphics for bug fights movies. He was an artist. Named Hormone Sekeni, his nick name was “Kanji”. He helped make these movies as a side project. Had never heard or seen anything like this before, but I showed him my interest, so one day he invited me home to have a look at his studio and work place. He gave me a DVD with Japanese Bug Fights. Now that I found it on Youtube, I recognized his motion graphics. It’s all his… For good or bad. 
I’m sure he doesn’t want this to be in his artist resumé, so don’t judge. Check his real art out and his crazy installations: http://www.super-blue.com/
Back to the bugs, watching the DVD I found my favorite bug. A small little critter, who’s mad as hell and takes on opponents, large and small, almost always wins. He’s in this video against a tarantula. Enjoy!
