doofhard, I too have come across some amazing 'fractal' blotter. White background, with blue, green, purple and red fine fractal line designs. Colours blend from green to blue purple to red, so some individual tabs look like the fractal is only one colour.
VERY VERY strong, a beautiful clean experience although two of my mates who are very experienced with acid were well and truly broken (manic tears, complete confusion and generally in need of valium) by the strength of these - they had a full tab, we had 1/2 or 3/4.
Sorry i can't report i agree the 'web' blotter, haven't come across it.
