Jurgen Brandt has presented us already a couple of times with some very nice puzzle designs.
One of his creations is a puzzle he calls "Edges Only".
Basically, it is a 333 cube without corners and with thin pieces (sheets) attached to the edge pieces.
Jurgen made a sample using metal sheets.
Pictures of that puzzle as well as pictures of some other of his new designs will soon be posted here (Wayne and I are working on a kind of survey article of his puzzles).
Below is a picture of a replica of the "Edges Only" puzzle made by myself using plasticard.
I am sorry that the quality of the picture is not very good.
Apparently the image-uploader doens't accept the JPEG pictures I made with my digital camera and I had to print and rescan the pictures in order to get them "uploaded".
For those interested, I have some more pictures (just e-mail me).
