The presentation made at TV ’04 was essentially the same as the final presentation to NIAC, available at:

www.niac.usra.edu/files/library/fellows_mtg/mar04_mtg/pdf/883Toth-Fejel.pdf

The only exception is a closer examination of a possible molecular prototype of the self-assembling Wang tile (see next slide).

The final report is at:www.niac.usra.edu/files/studies/final_report/pdf/883Toth-Fejel.pdf
