A whole lot of art today strives to do this, I believe. I'm mostly speaking of drawing here, characterized by semi-autistic painstaking repetition. Forced naiveté is very appealing in current work, and by forced, I mean those with MFAs channeling their inner child. Which is really nice, but when its bad, it can be disingenuous and twee. Check out, for instance, a great art blog Fecal Face I look at a lot and you'll get the gist of the spectrum. Or, check out this piece by Aurel Schmidt, whose work I like and instantly reminded me a bit of Wolfli:
*Ergo, all you young things, start making stuff like you're batt-shit crazy.
