More impossible

Yesterdays impossible triangle was intended as a casual joke to start the week... but it good a lot of good responses. Especially from those used to my normal haverings on Facebook. Therefore, I have decided to run a theme this week with impossible objects. And because this is 'LEGO Punk', and not 'Other stuff Punk', those objects shall be made from LEGO.

Although, because they're impossible objects, the 'made' tag may be suspect in a few cases.

But see what you can explain...
