If I had such a die I'd throw it millions of times, using the throws to reveal (slowly) to me some huge number. Then I would try to interpret the number; find something in it. Perhaps take it to encode a program, try to execute it, see if it outputs something. See if it halts.
@TetraspaceGrouping ha, perhaps ;)
random.org looks neat and old school, a combination I particularly enjoy :) thank you!
