I’ve been tinkering around in after-effects now for a while today/night and found that when they added extrusions in AE CS6 we actually got something that can emulate alot of the aerial-printing/slit-scan effects of those eighties really well.
What you need to do is simply extrude it a lot and then in the materials-options you set Transparency to a very high value. This will create those see-through walls and it can be animated in a simple way.
Now, if they only added options to curve extrusions. But using just the simple straight extrusion available I managed fairly quickly to animate a rudimentary Superman intro title. And remember, this works with other vector-layers too (logos) 🙂
