  • Simple Pattern GeneratorI'm pretty happy with this so very simple. 10 LET s=RND*16: FOR x=16384 TO 23296 STEP s 20 PRINT AT 0,0;s 30 POKE x,170 40 NEXT x

    Might work better with s=1+RND*16
    First time I ran it, s was .6 which was very slow and not a very good pattern!

    Also, better to be 16384 to 22527, to avoid getting odd attributes
