Go to www.hippopaint.com/ and type in your dA or tumblr name (or any name you go by online!) I found my stuff, my brother's... basically it appears to be a google-powered image search that returns black and white results.
If they had asked and given me credit and would show the painted results I wouldn't be upset.. They have a URL of my dA gallery at the bottom of the image.
But they didn't ask >(
They're back, there's a connected link on the hippopaint page - new link is hippopaint.fidsah.org/ When you search with your deviant art name, if you click on a lineart of yours from the deviantArt site a message does pop up
