TechCrunch had a great video showing off Autodesk Fluid FX on the IPad. The video is very trippy by Autodesk standards and I think the music gets ridiculously annoying after a few minutes, but Fluid FX is very impressive. Also at $1.99 you should get it just because its four decimal places to the right of other stuff you can get from Autodesk.
This marks another move by Autodesk into the mainstream. If they’re successful in this space then they’re going to look more and more like a wannabe “Adobe for 3D.” These moves put them up against Dassault and in my mind make them an a very tempting acquisition target for Adobe.
