Looks like really good stuff!
Is there a list of effects? I only see 13 of them in the animated gif on the page.
Also it doesn't give the dimensions of the effects or whether they are separate .pngs like your other work?
Yes the effects are separate PNG. The frames are mostly 16x16 but some go beyond that.
Here is a list of the anmations. Some are used in more then one effect.
