A pattern book of computer-generated extended crackle weave drawdowns by Ralph Griswold, dated April 27, 2005. A short introduction explains that a program varied the motif, tie-up and path at random, which produced somewhat longer floats than conventional crackle. The remaining pages are thumbnail drawdowns grouped by shape (square, wide, tall) and sorted by size, each labeled with the number of its downloadable WIF file on handweaving.net.
