I was wandering around the StarCraft2 site looking for inspiring screenshots. I found a few that I really like, and I’m wondering if Unity can create Force-field effects like these: ( Just the ForceFields )
Nice Fresnel effect on those purple edges!
You can do these forcefields with Unity, but I think the refraction effect on the bubble requires render to texture which requires Unity Pro version.

Sure…Unity can do anything (just some things are easier than others 
). I imagine it would involve a shader similar to the water shader, except using spherical mapping instead of planar.

I’d say it’s very similar to refractive glass shader, with added fresnel effect. So yes, Unity Pro can do that.
Hmm… Too bad it’s only available in Pro. 
Download the demo of “avert fate” on unitys homepage, they have created something like this!
