- Triangle pieces assembling into Batman: This was actually more impressive on 2nd look. At the beginning there's just 1 triangle (with some particles around it), but the shading on that triangle is not flat-shaded, it looks phong-shaded. This is impressive because phong-shading is a per-pixel technique, which the Amiga is really not suited to doing. (once more triangles appear, it resumes flat-shading)
If you look closely you can see the triangle is just a stencil/mask through to an image of a highlight that moves independently of the triangle. Stencil vectors? I think it's the same trick this awesome demo uses a ton (best at 6:30)...
