Sploid, Bob Ross, the world-renowned landscape artist, will be immortalized in a Happy Happy Video Game! All the actual artists I know are nuts about this guy; he's their Madonna, their touchstone and talisman, if not their benchmark.
With his preternaturally calm manner, his love of nature and a perfectly round Afro, Ross taught the world to paint "happy little trees," "happy little clouds" and "pretty little mountains."
We are lucky enough to live an age where his influence on the art world need never end.
