I made one a week ago and have been tempted to scramble it, but am not sure how to solve it.

Any ideas?

I have a pretty good idea how you might do the top half, [but I don't know how you're going to do the bottom half]

Please don't take this the wrong way (the joke is aimed at the Halfminx).. the method will be very similar to the megaminx method, and beginner methods have been discussed very recently: viewtopic.php?f=8&t=24865

Cheers,
Burgo.
