Perth - The DaVinci Machines

Mr DaVinci has come to town - though bereft of any codes that I can see. Someone has got hold of a load of his old drawings of stuff and built them. Kewl.

It's all screws, levers and pullys round here. This one lifts columns to their rightful place.
An Archimedes screw - insert innuendo here. Not sure what this is doing here, really, it would probably be better suited to an Archimedes exhibition.
This is an octagonal room all covered in mirrors. You could put something in it and see all round it - which would be good if you were a bit of a lazy artist like old Leonardo.
This, strangely, is a car and it's powered by springs - which would probably have meant that you would spend more time winding it up than doing wheelies. Perhaps LDV should have invented the internal combustion engine first the silly sausage.
A message from our sponsors. The message seems to be that we make stuff out of metal that Leonardo made out of wood, er, and metal.
The operating bits of an aircraft. The guy in it has just realised that the wings have fallen off and is taking the sensible precaution of ineffectually waving his arms around.
Leonardo's famous helicopter. These flying designs are all well and good but he seems to have little idea about power / weight ratios.
That's better; a glider modelled after a bat. That may well work, assuming that you climbed up somewhere high enough and the thing stayed in one piece.
The wing designs, themselves, are quite beautiful - in stark contrast to the faces of his test pilot squadron.
On to the war stuff, now. This is to get around the problem of ships heeling over when you fire cannons from them - a problem that all navies had. The idea is that you fire all the cannons at the same time and the ship stays, roughy, put. Couple of obvious points; firstly, you would have to hope that at least one cannon was pointing at something you wanted to hit. Secondly, this does not exactly engender fleet tactics; you have to make sure that all the other cannons are not pointing at something you don't want to hit.
A ship with a big, nasty spike on the front. It would put the willies up me, I can tell you - unless I had the fire-at-everything-all-at-once ship, above, of course.
Leonardo was a bit miffed at the lousy accuracy of the artillery of the time and went about redesigning it. Some pretty modern solutions, too.
Finally, the man himself and the most evil invention known to man. The push-bike. He probably invented the smug bastards that ride around them, too.
