Well, I was inspired by Fugu, so I wrote a variation of it called
"Fugu's Friend" that displays an animated turtle that rotates to face
the correct direction for movement, toggles fullscreen mode on
alt-enter, displays info such as FPS and current mouse position, lets
you toggle a 'game throttle' to avoid 100% cpu usage, lets you change
the speed at which the turtle swims, and lets you change paths whenever
you click, throwing away the old path and starting a new path.
I hope you find it entertaining or useful.
