AAron Lee has written more games than I have? I need to catch up.

Aravind Krishnaswamy has some cool astronomy pictures, plus an awesome gallery of animations rendered using his R.I.S.E. software.

Dan Pollock runs an internet hosting business in his spare time. He really is someone who cares.

Kenji Toyooka has a stylish site full of art.

Chris Mennie has a bunch of cool projects that he is working on.

Have Any Ideas?


   I have seen your investigation of devil's algorithm. And the
pre-specified moves should cover the entire space. That is, only using R and U
we may end up in an infinite loop (just an irrelevant thought :)). Also, If one
can by somehow study the cube with one corner cubelet fixed, then, he/she can
see how many rotations are required for each and every face color to attain its
proper location. The Least Common Multiple of all these numbers will give exact
rotations required for attaining the solution...   <21kalee@gmail.com>	---> A

Just a suggestion on the Pinhole lens that you created. If you have a spacer
mount for your lens used for macro photography, that may move the pinhole out
far enough to get a sharper image. I'm going to follow your great instructions
and give this a try as well. Thanks!

What is the phenomenon just before sleep when you hear an electric humming in
your brain? There is a very drugged like dizziness that I have to fight to
resist. How I become aware is a sense of ominous presence in the room but
tonight in particular it was outside the door of the room and outside the
window. Is this sleep disorder? Could it be contagious to a dog picking up on
my mental disorder? He is paceing right now and acting odd. I have this
experience quite often and it concerns.

One more thing. I should give you my email in case I forget to check back. I
suffer ADHD and this also might give you indication of something to answer. I
hear this electronic sound even when awake but it is usually- I can't think of
the word for it stealth? I also experience flashing lights. And sense or see
darker than dark forms when waking in the night. Am I crazy? my email is

My website is a strange place to ask this question, but anyway... what you are
experiencing is quite common, and called "Sleep Paralysis".  See
http://en.wikipedia.org/wiki/Sleep_paralysis for details.  When I used to
experience this, it manifested itself as if someone was drilling into the back
of my neck.  Not fun.

Your experience in Pinhole Lens is very interesting. I so try to make
one pinhole lens for D7000 and take some shots for fun.

I came across your investigation into the Devil's Algorithm in my search
for an answer to a similar question of my own - What is the smallest set of
algorithms that may be used to solve the cube, allowing for the cube to be
orientated between each algorithm (e.g. change which faces are T,R,and F)? The
answer to this is pretty trivial (any single rotation, then reorient the cube),
but if the algorithms must not be trivial then things can be more entertaining.

For example, here is a set of three standard algorithms that, with some
thought, can be applied to solve a cube: (upper-case letters for clockwise
Rotate 3 corners and swap 3 edges: tRTrTRTTrt
Rotate 3 corners:
Rotate 2 corners: rBRbrBRTrbRBrbRt

Normally these are used after
solving the first two layers and rotating the last layer's edges. Using just
these three, I was able to solve a scrambled cube - albeit much slower than
normal, but the thought process was more challenging than normal as I had to
visualize the movement of the cubies a couple of steps ahead.

Hi Mike:

I liked your CPP calculator.  Is there a way that you could use the
calculator for the CPP death benefit calculation?  I believe the principle is 6
months of the benefit that you are entitled to up to $2,500.  There are also
separate calcs if you are under 64 years old. 
My email is mike@eleganttributes.com.  Thanks!	Mike
