You might want to link to the two Arc4 flight trainers, also. I wrote mine in JavaScript and it's
here. If you want to put it on your site, I'll email you a zipped up copy. It's about 150k total.
There's an Easter Egg in the code, too. 10 click into the menu then wait about 10 seconds for the dim-bright-dim-bright error flash. Then click on the title "Virtual".
When I wrote mine, JPEG wrote one in Flash -- Peter made it a contest between us so he could get the best one. Unfortunately the spec changes were coming fast and furious while we were trying to create stable programs and Peter ended up with a short lived programmers' insurrection on his hands.
JPEG's certainly looks a lot better than mine. It's
here. The Easter Egg in this one is to click it on, type
coders, then click it off. You'll have to contact JPEG if you want permission to copy it.
