Triangular Magic Prism
This is the triangular prism analogue of Rubik's Magic Cube.
Java Applet Instructions

The Green Flag resets the puzzle.

Pressing the Spacebar scrambles the puzzle.

Down Arrow turns the bottom twelve cubelets by 180 degrees. The
same can be achieved by clicking on the top of the front center triangle.

Right Arrow turns the right twelve cubelets by 180 degrees.
The same can be achieved by clicking on the top of the right enter triangle.

Left Arrow turns the left twelve cubelets by 180 degrees. The
same can be achieved by clicking on the top of the left center triangle.

To turn one of the three corner columns (consisting of three cubelets each)
by 180 degrees, click on the top
corner triangle of the upper cubelet.

Pressing a turns the top layer by 120 degrees clockwise.
The same can be achieved by clicking on the leftmost face of this layer.

Pressing y or z turns the top layer by 120 degrees
counterclockwise. The same can be achieved by clicking on the
rightmost face of this layer.

Pressing s turns the central layer by 120 degrees clockwise
(as viewed from above).
The same can be achieved by clicking on the leftmost face of this layer.

Pressing x turns the bottom layer by 120 degrees counterclockwise
(as viewed from above).
The same can be achieved by clicking on the rightmost face of this layer.

Pressing d turns the bottom layer by 120 degrees clockwise
(as viewed from above).
The same can be achieved by clicking on the leftmost face of this layer.

Pressing c turns the bottom layer by 120 degrees counterclockwise
(as viewed from above).
The same can be achieved by clicking on the rightmost face of this layer.

Klicking on the top of one of the central edge triangles turns
the entire edge/side by 180 degrees.

Pressing q flips the entire prism over by 180 degrees
in the direction back > right.

To solve the prism, you have to get the top side yellow,
the left side blue and the right side red. (The green back and the white
bottom are invisible.)

When you have solve the prism, your time taken is displayed
for 5 seconds.
Solution Strategy

A complete strategy still needs to be worked out.

Interesting things can happen here. For instance,
exactly one pair of central side face triangles
can be interchanged.
