Mark Bell is an Author, Artist, Illustrator, Musician and Theoretical    Scientist - though in theory, his science isn't very good and his  theories leave much to be desired. In fact, it he tells you to mix two  chemicals together... Don't do it! You might also wish to ignore his  theory about how llamas created and built Stonehenge.

 Mark is a member in poor standing of: The Imaginary Llama Club  for the Crazily Insane, The Prague Institute for Troubled Physics,  The Occult Brotherhood of Hopping Squirrels, and a Secret Society  that can't be named (because no one ever said what the name was).

 Mark has written such books as: "The Trouble with the Prague  Institute for Troubled Physics", "The Invisible Book That Couldn't be  Found", "Ooops, I Shouldn't Have Mixed This Stuff Together" and  more (or less)...

 Mark has illustrated such books as: "The Trouble with Illustrating  The Trouble with the Prague Institute for Troubled Physics" and  "Trying to illustrate an Invisible Book That Couldn't be Found".

 Mark has a little friend named "Purple Bunny" (a.k.a. "Purply Poo  Bunny") who sometimes takes credit for writing Mark's stories and  books.  Just saying...
