Christmas Tree Project

Hello,
I'm having problems with my Christmas tree project and I need help. I'm Trying to group up certain LEDs To do 1 task. Under the OBEX category I wanted to test out 1 of the interesting LED set ups up there. Its called jm_bam_rgb under the LED category. http://obex.parallax.com/object/301 (this is the link). I just want to know how to make at least 22 LEDs light up using this. If this is done then I want to know how to group them. Which means how would I get more than 1 LED to light up and pulse in a group of at least 7. My teacher was a little stumped so I wanted to know if someone out there could help me. If someone could reply that would be great. If so write back please. Thank you.

Daniel Harris of Parallax posted a 32-output PWM driver that will probably be useful. I frequently have multiple Spin cogs writing to an LED driver.
