Subject: My new favorite IRP puzzle

Grab the latest<http://www.gravitation3d.com/magictile/downloads/MagicTile_v2_Preview.zip>for
two new sets of puzzles, based on the {6,4} and {6,6} IRPs.

*The {6,4} is great!* There are not too many colors (eight), and the tiling
is less dense than some of the others, so it results in a balanced and
workable puzzle. I solved the vertex turning version tonight using the IRP
view, and it was a lot of fun :D As Melinda writes on her page for
this IRP<http://www.superliminal.com/geometry/infinite/6_4a.htm>, it
"can be seen as a packing of truncated octahedra". Here is a picture I
snapped<http://groups.yahoo.com/group/4D_Cubing/photos/album/793135570/pic/706741332/view?picmode=&mode=tn&order=ordinal&start=1&count=20&dir=asc>
early
in my solve.

The {6,6} stretches the hyperbolic to IRP texture mapping a bit, and the
slices take on interesting parabola-looking shapes. It still works pretty
well though.

Take Care,
