Do you guys think these are good ideas?

The Train

This train has four sets of eight wheels. Each wheel is split into two identical halves. When all of the halves are both properly matched AND in the correct holes, all of he wheels will turn. But if some aren't, they will either not move or will have limited turning. Can you get all the wheels to spin freely?

The Big Switcheroo.

This puzzle is a sliding puzzle using a 15 puzzle board with opposite corners removed. The edges are all blocked out so you can only see the four middle pieces. You can not touch the pieces, you can only tilt them. Can you match all the center pieces? can you flip their colors?

Slide Cube:

a 3x3x3 frame has sliding, um, tape going around the 1x1 sections. Each tape weaves over and under the others in a NON-SYMMETRICAL pattern. Each tape has the Rubik's Cube colors on it. When solved, the puzzle looks like a solved Rubik's Cube. When scrambled, the puzzle looks like an unsolved Rubik's Cube. Can you bring the puzzle back to its former glory?

looks like the last one would be pretty simple to get a prototype going, would love to see it!

I love the idea of the last one, too. I think the non-symmetrical weave would bother me, though.

It would make it a more difficult puzzle.

I know, it'd just bother me a bit. A little OCD for that kind of stuff.

I don't imagine that it would be too difficult of a puzzle in the first place, though.
