Colour Clash Attack ;)
 
Take a look at this listing from the Spectrum Basic Programming manual. It draws some colourful lines however the effects of the colour clash (partly it was written to demo this 'effect' I think) are quickly shown...

Lets take a look of it "in action" , video's are < 40 seconds so quick to watch.

Now lets take a look again, this time with a small tweak...

There's no prize for figuring out how I did it though unfortunately. :)

The same routine (with a tiny tweak to the 'limits' and changing it to COLOUR x) works on the BBC Micro too which does not have colour clash in M2 although its low res so it looks blocky(ish) on that.

 

I must try to do this on the Oric / Dragon and Amstrad too. I do not think I can figure out the odd Basic on the C64 as it appears to involve a lot of odd symbols. I guess I should hunt down a Basic Programming manual for the C64/C128 to work it out.
