ok, so im really new to this so help me out here. ;D
i just got some TLCs the other day i was wondering where i should start with the code.
ive already used the libraries for fun.
i just wanna know how i could use RGB leds and write code for that.
where do i start?
Take a look at one of my projects:-
http://www.thebox.myzen.co.uk/Hardware/Mini_Monome.html
This uses an early version of the library hacked to allow multiplexing with the chip.
very nice i like your project 
but my next question is ..
please excuse the ignorance :
but what exactly is multiplexing, and how would i go about doing that with the TLC5940 as far as coding ?
i have it all hooked up like the example on the arduino site
my final goal would be to control RGB led's and and to make patterns with all of them.
but what exactly is multiplexing
It is the rapid switching on and off to make it look like they are on all the time. It is short for "time division multiplexing" and is a trick to control lots of LEDs with a lesser capacity controller.
It's the way most LED matrices work.
