Wasting Time: Graffiti Any Website With Goggles
Goggles is an open-source bookmarklet that allows you to MS Paint-style graffiti any webpage. You just go to Goggles, drag the link to your bookmarks, then click on it after you're at the page you want to graffiti. Left click draws, right click and dragging across a line erases it, and clicking the bookmark again removes the graffiti app altogether. This is what I did with Geekologie. "HOLY SHIT BRO!" I know, I almost want to marry it.
Thanks ShadowSushi & Tacos4u, an unlikely combination, but unsurprisingly delicious.
