Probably wasn't completed.

I dunno, I can semi agree with you, but I basically think "If it takes more than 3 builders to make one ledge, ditch it". That's because I rather like levels which depend on short bridges being built with good timing.

You've experienced a broken arcade machine?

That's me. I'm running Safari 4, and love it. Many people dislike it. Can't see why. Nothing implicitly wrong with it.

It's still a good solution for the crossplatform software, with simplicity in mind. Of course, if you would like a hand learning C#, I'd happily help.

Easy on OS X. Just double clicked, it ran. :-) Ran into an error when I attempted to enter invalid data into the input system. Next step, error checking.

Here's my adaptation of your calculator in C#. Boy howdy, does it look different, lol.
Attached is also the binary executable. You can simply double click this to run in Windows.
On Linux or Mac OS X, make sure you have Mono installed. Then open a command line, navigate to
the folder containing the EXE file, and run this command.
mono ConsoleCalc.exe

Not many places at the moment, since only Safari and Mobile Safari for iPhone and iPod touch support it. It's supposed to become a standard later on, which I'm hoping for. If you're ever able to see what the 3D transforms can do, it's actually really cool that it can be done without the use of something like Silverlight or Flash Player (which both suck if you don't use Windows, and SL isn't even available on Linux proper).

Just something we had to dig into at uni. Experimental web standards, their impact, and showing one being used. I made a little thing where text revolves on a merry-go-round, with the haunted merry-go-round music from Super Mario 64 playing in the background.
