It’s a comic about life, science and ghosts. Sometimes has potty humor. Sometimes is geeky in the sciencey kind of way. Not very mathy though :-|, and doesn’t seem to update often.
My favorite from that site (click to visit the site):
Another good one from “the usual ghosts”:
2. Peebles Lab
Physics related webcomic. Very mathy. Also very good. I”ll probably write more about it in the future ^_^. Check out a sample below which starts a short series called the “Derivative Series”. It’s a fun read.
