Sort-of-flying machines?

I note with glee that the Ukraine hosted the latest round of the Red Bull Flugtag competition last weekend. The aim of the event is for teams to build a flying machine (or, at least, something bearing a vague resemblance to one), and to compete by jumping off a ramp into a river or harbor, to see which creation 'flies' the furthest. Here's the advertisement provided by Red Bull to publicize the event.

There were some weird and wonderful creations this year. Here's a small selection from the photographs provided by Starcasm.net .










There are many more pictures at the link. Looks like a lot of fun was had by all.
