You can slip thru to the slightly out-of-date Imagine (tm) lighting tutorial, and IML member site list.
Soon, well, hopefully soon, there will be a bunch of new stuff, such as a tutorial about what can be done with specular glints in Imagine.
The image above was created by placing 480 very low intensity 1/R fall-off colored lights just above a slightly rippled transparent specular disk.
A route into a gallery of my older images is still available.
