Basicly this simple employees a HEAP of <big> tags and only requires a

Proof of concept

Mozilla doesn't crash some version my experience high cpu usage while
rendering also the layout will be stuffed but it is also a problem with
overflowing font sizes.
Opera untested.
Other untested.
Tried it twice, crashed IE 5.0 (didn't know I still had it on my hard drive)
under Mac OS 9 both times and took the whole system with it (OS 9 doesn't
have any memory protection etc).


Nice work.
