So I've been playing with channel F programming today, seeing if I can get an object to move without a trail behind it. I don't know why, but it seems as though apparently it doesn't clean up previous bitmaps after drawing them? This discovery was used in Kevin Vs. Tomatoes. So I made a second object trailing behind it the same color as the background. This technique works pretty good. So I made this program of a spaceship travelling left across the screen in a dusk sky with the ground below. It's like Space Jockey for the Atari 2600. If I plan to make a game out of this, that's what I'm basing it on.

But for now, I'm just goofing around to see if I can get an object moving without traces of it behind. I'm still wondering how many objects the Channel F can have onscreen at once. I'm guessing quite a lot due to Alien Invasion.
