Innovation on the Edge?

MCassatt asks: "It's a truism in many fields that breakthroughs come from the edge: the scandalous Impressionists become pretty pictures for posters and umbrellas; the world of science fiction becomes the world of science. The wonderful, the fantastic, and the mad of today are tomorrow's mainstream. Are there examples of this in computer science? Not extreme programming, but extreme programs?"

Personally, I'm amazed that there aren't more p2p worms/remote exploits out there.

    These machines and programs jammed an enormous amount of programming functionality into incredibly tight spaces. Many of the old arcade programs ran on 4K, 8K, or 16K 8 bit computers, and ran on machines with clock speeds of under 1 MHz, and effective instruction rates of mere hundreds of thousands per second. Even a fully loaded Apple II gave you under 32K of actual program space to work with, once you subtracted the low RAM, the hires graphics areas, and the BASIC ROM space, and people did a whole lot with that 32K.

    The last two games I've purchased (Simcity 4 and C&C Generals) require minimums of 500 MHz and 800 MHz processors respectively and 128M of RAM. Of course, they do a lot more, but they are certainly not 500, or 800, or 8000 times as entertaining as the Cocktail Space Invaders machine that graces my hall entryway and is such a hit when we throw parties.

    Early arcade games were heroic, wildly successful efforts. Truly examples of extreme programming.

    Without a doubt, video motion detection is going to be huge. Programs like Homewatcher, GOTCHA, and many others (I'm too lazy to set up links) can sense motion very accurately, take timestamped images, upload them to a webserver, send them via faz and email, call your phone, run external programs, etc, etc. If you live in a dangerous neighbourhood like me(and if economic downturns persist, perhaps you soon will) they are hugely useful. Couples with cheap cameras and cheap low power hard drives, systems like this could make crime very dangerous for the potential thief if they were extremely widespread.
