Help! PIC Controlled LED Array Circuit - 100 LED's??

I am new to electronics, but a programmer by trade. I am trying to
achieve a circuit of up to 100 independently controlled LED's (not
segmented display modules). Ideally the circuit would be controlled by
one or more PIC microcontrollers as I have a Willem II programmer. My
application is artistic in nature and requires the leds to be spread
out over a wide area as opposed to being in a grid formation.

I have heard a lot of conflicting reports about Maxim's MAX721xx chips
for this job. Some say it's the one I want, but others (including an
actual Maxim tech-supporter) say it's more suited to the segmented
displays. I have experimented with this chip with little success.

Has anybody achieved anything like this? I have scoured the Internet
and newsgroups for literally weeks looking for a matching schematic
and source module. I have found a few Basic Stamp modules but I'm not
setup for that at all and would rather stick with native PIC. The only
compiler I have is MPLab's MPASM.

Many thanks to anyone that can help
