It's been way to many years since I've taken any LSD.
One of the sample scripts that comes with Processing (processing.org) does this.
Yeah, it's gotten WAY deeper since I looked at it a couple of years ago.
This really makes me want to project live slit-scan video of the audience behind the band next time I play out.
Ok, the sample code that comes with Processing is pretty weak, but a much better one is here:
I jsut tried it and it works really well. If you're running Windows, you'll need to install v1.0.1 (NOT the earlier or later versions!) of WinVDIG from here: http://www.eden.net.nz/7/20071008/
Don't expect it to look this good in real time, though - you need to shoot at pretty high speeds to get it to look like this.
Alas I am but a tourist in that world. I've been wanting to incorporate Processing into a workflow for a project but I havent had a timetable that could accommodate the learning curve.
I have some friends who use it, and I am blown away by it.
Matbe try PD/GEM? It's comparably powerful but since it's a Miller Puckett project it has a graphical "flowchart" type interface familiar from Max/MSP. I've got more experience with CSound than with Max/MSP, so Processing makes more sense to me personally (not that I'm very good at any of it), but they're both fantastic.

I got all the way through this without puking!
Is this a scanline camera or something different
It's a post-processing simulation of traditional slit-scan motion photography (i.e. the ending of 2001).
The source material is just standard video, if you follow my link above to the Processing website there's sample code to do it in real time from your webcam, and the Youtube description for this video has an Apple app store link for a basic, offline slit-scan program that costs . I think there's an iPhone app, too. Bein able to do this in real time is fantastic.
It's how they did the Dr. Who time tunnel, too.
I thought that was just video feedback of a monitor for the camera. It was slit scan, too?
There were a bunch of variants, the old ones used video feedback but in '73 they did the slit-scan version, which is the one I used to see most often when I watched reruns as a kid, and also corresponds to the Tom Baker period, which was always my favorite.
Fantastic... I would love to use this effect in a film.
I wonder, if you had a machine capable of processing at 200-300 fps in real time, if you could get results this smooth with live video.

The unsettling Basinski-like music goes well with this
This wouldn't be psychedelic without it.
