VBPaint (New 65-pattern 1-bit Dithering)

Can you believe that that picture contains only 2 colors? Because I strove for pure VB, it's quite slow, but the results for a picture like this is well worth it. The 691x864 GIF is only 13.4 KB. I have increased the palette to 65 patterns (simulated 6-bit) from the last version of VBPaint, which had a palette of 17 patterns (simulated 4-bit).
