I just met someone who told me he watched the beautiful, hour-long documentary (costs a dollar on Vimeo), and after some research into the various methods of tying (and a conversation with his open-minded rabbi), he just ordered his first pair of Techeiles (via Uzechartem’s heroes, to subsidize the cost).
Ha ha ha. It works!
From the blurb:
The documentary discusses how it was lost, the search for the chilazon, and the reasons to believe the murex trunculus was the source of the dye. The documentary also includes a balanced discussion from a traditional Jewish perspective as to whether one should wear Techeiles in our days.
