T.W.M. is March’s program of the month. It is a simple animation that tries to mimic a computer’s destruction of its defined target. February was actually pretty prolific for me as I transcribed this and another program, as well as updated a number of older programs using MCODER. Fortunately, that means I have a few more programs available than I normally do. Of course, one is more than I normally have ready so I’m not sure that means much. Anyway, go give it a try and enjoy the animation in all its simplicity.

February is upon us and that means another program of the month. This month it is another one from 1983: Light Walls. In case you hadn’t guessed, it has its roots in Tron. The game requires you to steer right (“.”) or left (“z”) to avoid hitting the light walls. I wrote this program while a friend was over and we took turns trying beat others high scores. Who says you need color and 3D graphics to have a good time! Not convinced. Give it a try yourself and see how good your reactions are.

Short and sweet. Monthly mini-build for Jan 2012 rendered with POV-ray. Interesting that these in-store promotions are now numbered. 40036 Cobra by SafePit, on Flickr

Welcome to the new year! Starting off the second season of monthly programs is January's program Road Hog. Road Hog is a driving game similar to my later Flywheel game. I hesitate to call it a racing game as there is no acceleration. You just move the car left or right using the Z or . keys. The game is pretty easy due to the slow speed of the animation. Go give it a spin.

Well, the celebration of thirty years since the introduction of the ZX81 is now over. For the last year I've been bringing you an original ZX81 program each month as a tribute to my first computer. It was a lot of fun typing in those old programs or fixing tape recordings I made back in the eighties. I even rewrote one which brought me back to those old programming days. For those that found your way here, I hope you enjoyed my ramblings about the programs. Perhaps you've learned something or I just invoked a kinship from a fellow programmer.

It's a rainy Saturday afternoon which provides a perfect opportunity to render LEGO's monthly mini build with POV-Ray. Bird by SafePit, on Flickr

I did it! After a lot of recording, cleaning, and tweaking I was finally able to get Water Bug II loaded! Hit the link, wait for it to load, then hit enter to give it a whirl. Then use the 5, 6, 7, and 8 keys to move (left, down, up, right) just as they are on the ZX81 keyboard.
