Do a barrel roll -- with the IOCCC flight simulator (banks 1998) I'm running it under cygwin and it's really entertaining

; scanf("%lf%lf%lf",y +n,w+y, y+s)+1; y ++); XSelectInput(e,z= XCreateSimpleWindow(e,z,0,0,400,400,
0,0,WhitePixel(e,0) ),KeyPressMask); for(XMapWindow(e,z); ; T=sin(O)){ struct timeval G={ 0,dt*1e6}

It uses X windows and compiles using the following

#! /bin/sh
cc banks.c -o banks -DIT=XK_Page_Up -DDT=XK_Page_Down \
-DUP=XK_Up -DDN=XK_Down -DLT=XK_Left -DRT=XK_Right \
-DCS=XK_Return -Ddt=0.02 -lm -lX11 -L/usr/X11R6/lib

I also was procrastinating doing java coding (:rolleyes:) and I learned how to use autoconf tools! Pretty awesome I think -- I survived make distcheck so I'm pretty happy. Here's a link if you want my autoconf setup

banks-1.0.tar.gz - zxcvbn - ioccc flight simulator - Google Code (http://code.google.com/p/zxcvbn/downloads/detail?name=banks-1.0.tar.gz)

Basically the usage is that it contains these scenary files and you run it like so --

cat horizon.sc pittsburgh.sc | ./banks
cat mountains.sc bb.sc | ./banks

Try it out :)

That is very cool!

And I got an integer overflow :D. (I think that means I crashed or something)

Yea I think so, the crashing sequence is so funny it tumbles and then int overflow

Barrel roll :]
