hi all!

i'm just starting in on a new website for a client. the logo is etched in stone. i want to have the logo fade in but while that is happening a want a dust windblown effect to happen over the logo...like you are seeing a fast time sequenced event that has taken years to occur (ie; it's taken years of the winds blowing to carve out the logo in the stone).

does anyone have any suggestions for this that wouldn't bog down a viewers rig...it would only happen upon first entering.

thanks so much.
