I am curious as to which version of QB64 was used to make the fractal? Reason: Version 1.3, on 'my' Linux machine, produces a single multi-coloured diagonal line that begins in the top left of the screen and ends in the bottom right. All I did was 'copy and paste' and F5. If it's just me, then by all means, ignore the ravings of this user and pretend that I didn't post... lol
