Hi,

Thank you, I am glad you are liking it. Melinda had suggested doing a piece finder where clicking on a sticker makes the program find and highlight which sticker should ultimately go there (this would be an inverse function to the current ctrl+shift+click capability that highlights where a clicked sticker should go). This will be easy and I plan to do it (I'll probably get another version out in the next week or two with that and some other nice suggestions Melinda made). The new piece finder could highlight single stickers or all the stickers of a piece, and I'm leaning towards the second possibility. I think Melinda's suggestion will be a better functionality for this puzzle than doing an MC5D-like piece finder because the latter requires the user deal with all the face colors.

Thanks for the suggestion of numbering/patterns on stickers. I agree that would be nice, but it will be more involved to program. So even though I would like this too, I'm going to have to add it to the long term wish list for now (it's going to take some investigation on my part to figure out a good way to do it - I think the solution may likely involve texture mapping). Hopefully the extended piece finding will be enough for the short term. Thanks again for the feedback!

P.S. There were some ugly rendering issues I noticed since the first upload, which are fixed. If any of you are playing with this and seeing them, you might want to grab the latest.

Hello Roice,

I really think this is an amazing program and I will definitely
attempt to solve it, but for me, looking at 120 different colors is
just too confusing, so I thought it might be easier if each color had

a number or some type of distinguishing pattern it so there wouldn't
be so much confusion between the colors. Also, on the MagicCube5D, I
really liked the piece finder, and I think it would make the 120 Cell

much easier if there were a piece finder in it. Just a couple
suggestions, but great job creating such an awesome puzzle!

I have to add my voice to the rest in expression of awe at this
p=
uzzle. It's been years since I've even done mc4d -- my life has
gotten b=
usier. One day maybe I'll try it, and I'm sure I'll
eventually play arou=
nd with it just to see what it feels like. As
with many of the other par=
ticipants on this list, I have always had a
special affinity for the 120=
-cell. It always seemed to me that it
sort of snuck in to the regular po=
lyhedron list, just barely fitting,
kind of like the pentagon just barel=
y being able to be the face shape
of one of the platonic solids. :-) Do =
I recall correctly that this
polyhedron is its own dual?

My recollection=
of solving the megaminx is that you can do all but the
last few steps a=
s localized solutions. Each twist affects such a
small number of pieces =
that the constraints don't play a big role
until the end. It seems that =
each twist would necessarily alter
pieces on the 12 adjacent cells.
<=
BR>I don't find it surprising that five random twists would result in
so=
me interacting pieces. The first twist affects pieces on 12 of
the
120 cells, not including the cell twisted. In order for the second<=
BR>twist to not interact with any pieces, it must be on a cell that is
n=
either any of the 12 affected faces nor adjacent to any of them
(except =
that it could be another twist of the first face). I'm not
sure how many=
cells that is. If you managed to get one, there are
even fewer places f=
or the third twist. It seems to me that the number
of twists after which=
there is some guaranteed interaction must be
very small....maybe three =
or four? I could probably work it out, but
I imagine others on this list=
could do it faster. My "math chops" may
be good compared to the general=
population, but not compared to many
of the readers of this list. :-)R>
Anyway, the 120 cell puzzle is a work of beauty!
