Had the same t-shirt with the barcode readable source code on it. I think prompted by seeing Greg Rose wear one, may have gotten it from him/mutual friends. As an foreign citizen I was never brave enough to wear it through a USA entry airport.

i seem to have vague recollection of a variant of this shirt that had a perl script on it? or was the perl script for decoding the barcode?

Haha I remember that. OG fist bump!

Cane to say the same thing. It sparked a lot of interesting conversations over the years.
