Ostrich Legos! O!S!T!R!I!C!H! L!E!G!O!S!

Between this and a good set of lego knights you could build a recreation of joust with legos!

Throw in a few mindstorm kits and you could motorize the whole thing.

Cost is approximately $10 per ostrich.

Available for purchase here.

I plan on ordering some at some point in the near future. Even if I never do anything with them, Ostrich Legos have to be one of the coolest inventions ever.
