Zebra Girl
After seeing Grant's little rant supporting the excellent Penny Arcade I decided to rant a bit about my current favourite online comic, Zebra Girl

When three housemates find an Ancient Tome of Evil in the attic ("These things always turn up in Attics") and one of them summons an ancient evil (2 inches high), things go reasonably well until after the dispelling ritual someone slams a book and converts another housemate into a three eyed, tailed, horned, hooved and striped demon.

Somewhere along the way it starts developing a plot that continues today.

The artwork is just exquisite, the jokes dark, the plot amazing.

For a single teaser panel? I choose this

The latest story arc (with a gathering of magic, a betrayal, a power up and a reckoning) had me checking a comic I know only updates weekly 2 - 3 times a week, JUST IN CASE!

Excellent!
