As mentioned previously, one should see the terrain of Mars in 3-D. There's nothing quite so spectacular on Earth-- well, except the water features.
I stumbled across some 2-D to 3-D conversions of famous art. Due to digital graphics processes this sort of thing can be done to a high degree of perfection. Some prefer the old stereo side-by-side picture technique (it does preserve the colors), but the anaglyph pictures are interesting too.
Here is the anaglyph tower: www.jim3dlong.com/anaglyphs-art-26.html
Some of the other images on the site are worth exploring. In general, when converting a painting to anaglyph, the layers appear flat, and human figures are cardboard like cut-outs. This collection of anaglyphs, however, has some striking exceptions to this.
The "Mona Lisa," for example, appears as though standing, or sitting, before you in a field at dusk. The atmospherics of the distances adds something palpable to these paintings, although I am not of the opinion that this gimmick at all elevates the quality of the art. Still, it is as if placing the art back into the real world-- just add water, er, magic glasses to bring the reality back to life. "Another World II" and "Rind" by Escher, one might argue, are actually improved by the 3-D. Escher must have anticipated this.
