Short intro challenge 20 line fractal

[Shockwave]

Taking the Keftales and the Axial on a bit, also I've seen the Xor texture used in this comp, I decided to see if I could squeeze a proper fractal into 20 lines, I managed to squash the serpinski gasket down to 18 lines, could get it to 17 lines if I lost the windowed mode.

#define PTC_win
#Include Once "tinyptc.bi"
If( ptc_open( "DBF 18 LINE SERPINSKI GASKET FRACTAL BY SHOCKWAVE", 800, 600 ) = 1 ) Then dim shared buffer(800*600) as integer,points(1 to 8) as integer => { 400,5 , 5,595 , 795,595 , 400 , 5}
do     
    for n=0 to 250
        buffer((points(7)+(points(8)*800))) = rgb(n shr 2 ,n , n shr 1)
        r=int(rnd*3)+1
        if r=1 then
             points(7) = (points(7) + points(1))  shr 1
             points(8) = (points(8) + points(2))  shr 1
        elseif r=2 then points(7) = (points(7) + points(3)) shr 1
            points(8) = (points(8) + points(4)) shr 1
        elseif r=3 then points(7) = (points(7) + points(5)) shr 1
            points(8) = (points(8) + points(6)) shr 1
        end if
    next
ptc_update@buffer(0)
loop until inkey$<>""

And here it is again, I have squashed this further, doing away with 5 lines to enable me to add some nice colours and rotate it in a nice way.
It's sort of a fake textured poly thing now


Still in 18 lines!!

Good oneÃ,  
if only you could subdivide polys to fill them in

Good oneÃ,

Or change colors like a plasma effect... But still very smart for 18 lines of code

Thanks guys
