C64 Demo: NINE by Iftkryo

The demoscene is a rich source of awesome, and at times ridiculous, imagery and sounds. Once in a while we sift through it to find things to entertain you with.

On Youtube, some Commodore 64 observers have been in a bit of a tizzy examining a new demo by Iftkryo, called NINE (3m).

If you don’t know anything about the computer, it might not seem too interesting. A block-graphics wizard lifts his hat and out comes nine large digits in different colors that then float around the screen.

The more you know about the Commodore 64, though, the more interesting it is. The machine’s graphics chip, the VIC II, is can only display eight hardware sprites at once. Then the sprites cluster together on the same scanline, meaning ordinary multiplexing can’t be happening. Then they drift up into the upper boarder. It demonstrates complete mastery of the hardware, doing a lot of things that simply shouldn’t be possible.

Iftkryo has produced a video giving away his secrets, closely explaining how the demo does its magic (22m):

It’s a good exploration of a number of weird C64 graphics tricks: sprite multiplexing of course, opening up the side and top boarders, and making productive use of mysterious graphics that appear off the top of the screen if the boarder is gone. While little code is shown, it’s definitely on the more technical end of things we present here. I’d give it a four out of five on Drebnar’s Geekiness Scale. But if you like learning about obscure tech details of a forty-year-old computer? And who doesn’t? There it is!

Demoscene: La Linea

The demoscene is a rich source of awesome, and at times ridiculous, imagery and sounds. Once in a while we sift through it to find things to entertain you with.

Demos aren’t necessarily out to wow you by pushing a computer’s hardware to its absolute limits. Sometimes one will just present something that was obviously (to people who understand the platform) challenging to do, but is fun for its own sake.

La Linea is a series of short films made for television created by Italian animator Osvaldo Cavandoli. They may be familiar to 80s kids who watched a show called The Great Space Coaster, as they were in regular rotation as segments on that show. They feature an expressive and excitable character, known as “Mr. Linea,” who speaks gibberish and has a variety of adventures, despite the fact that he and his world are represented (with some cheating) as contortions of a single horizontal line. The character often speaks to the off-screen animator, asking for various items, devices and, occasionally, other characters to interact with. Every cartoon ends with the main character falling off or through the line in some way. Some of them are collected on Youtube. Here is an example (2 1/2 minutes):

In 2002, the demogroup Breeze made a tribute to Cavandoli’s work in the form of a full-length La Linea cartoon running on a Commodore 64. It doesn’t have the distinctive music or the gibberish, and there’s no photorealistic hand that reaches in to draw parts of the scene, but the style is otherwise faithful to the original. It is a remake of La Linea #10. Please, enjoy (3 1/2 minutes)!
