Thanks very much, both for your support, xebra, and your idea, blueblaze. I contacted a friend who has a webcam, and he'll give it to me at school tomorrow. So, assuming I can set it up quickly, hopefully I can upload it here soon.
Brian, I'd be interested to see how you do it. Do you allow Robotnik to fly up a second time? If so, that's why your time is >54 secs. Otherwise, I'm not sure. It took me well over 60 tries to get done the first time with my strategy, and perhaps anoter 30 until it was perfect, so don't expect it to come easily!
Edit: Can I also attach it onto here? It does say:
You may attach a file to this message.

...although I figure that's more for pictures and whatnot.
