Rolling Tag Cloud for Mac

Hi,
I am new to the Mac experience and totally loving it mostly.....
Whilst i had understood that Mac's are the most and best, the last word in easy to use innovative computer experience,
I am struggling with the following;

Have been trying to find a code that i could apply to iweb 08 for display on my websites to host a 'Rolling Tag Cloud'
If anyone has not encountered these yet, please look here
Rolling Tag Cloud
I would be very grateful to any adviser :}

n.b I am also having diabolical trouble in applying any Falling Snow effect to one of my websites
The London Snowman
and again, any advice??
Other than these issues,
I am loving the mac!

Apologies for wrong Forum, & Thanks.
Besides that useful bit of Re-Positioning....
Does Anybody have any idea about applying Rolling Tag Clouds to iWeb 08???
Or should i consider saying
"Hi im a P.C. and i can do things a Mac cant even consider...."
