Rinpa Eshidan is a collective of Japanese artists including Daisuke Yamamoto and Noiz-Davi. Unfortunately, outside their website and postings on YouTube, I don't have much information on them. Their website features some nice work in the gallery, some interesting time lapse videos, and what has to be the most relaxing of homepages.
Even if the resulting artwork isn't your cup of tea, the techniques are certainly interesting and it can't be denied that they enjoy it. This clip is a good example. It's entitled Puzzle and they work on a quartet of canvases which form a single frame. As they progress through the painting, different canvases are rotated for some interesting effects.
