From a physical Tamariz deck this is how quickly and accurately to physically create a wrapping 52 card DeBruijn deck (assuming Hearts and Diamonds are binary "1"'s). Note that a spectator can initially cut this deck as many times as they wish then deal one card face down for himself and five more cards face down (one for each of his buddies). All 6 spectators peek at their cards without revealing them to anyone. The cards and deck can be hidden from the magician at all times. The magician asks a few simple questions then accurately names all 6 cards!

To perform the Leo Boudreau's "Eyes closed if you have a red card" trick with this wrapping de Bruijn deck you will also need a full crib sheet. Therefore during performance after each of the six spectators have their card in hand (and you know the octal pattern of the six cards by looking at the six spectators' eyes) I openly use a funny titled book named "ESP Made Easy" to look up the octal code crib sheet info.

This gets a chuckle from the audience because they think I'm pulling their leg to get a laugh with such a funny titled book. There is no such book, I just bought a thin dollar book from Goodwill and created and printed my own simple title page and glued it on the front and glued the full crib sheet info on page 50.

Below is the six step procedure to convert a Tamariz deck to this P7 DeBruijn 26-26 (1s and 0s) deck.

Normal Tamariz:

4C-2H-7D-3C-4H-6D-AS-5H-9S-2S-QH-3D-QC
8H-6S-5S-9H-KC-2D-JH-3S-8S-6H-10C-5D-KD
2C-3H-8D-5C-KS-JD-8C-10S-KH-JC-7S-10H-AD
4S-7H-4D-AC-9C-JS-QD-7C-QS-10D-6C-AH-9D

Way ahead of performance time starting with above Tamariz deck:

1. move 3c-4h (pos 4-5) to after QC (after pos 13).
2. move 10d from pos 49 to after the 9s (after pos 7).
3. move 3s-8s from now pos 22-23 to after 6c (after pos 50).
4. move the 4c (pos 1) to after the 8h (after pos 14).
5. move 2c (now pos 25) to after 4d (pos 40).
6. move 7s-10h (pos 35,36) to after 4s (pos 38).

Result Tamariz P7 wrapping de Bruijn deck (based on red cards are "1"s):
2h-7d-6d-As-5h-9s-10d-2s-Qh-3d-Qc-3c-4h
8h-4c-6s-5s-9h-Kc-2d-Jh-6h-10c-5d-Kd-3h
8d-5c-Ks-Jd-8c-10s-Kh-Jc-Ad-4s-7s-10h-7h
4d-2c-Ac-9c-Js-Qd-7c-Qs-6c-3s-8s-Ah-9d

P7 de Bruijn below based on P from TomasB (note that I'm specifying hearts and diamonds as binary "1" whereas clubs and spades are binary "0"):
1110101011001
1000101110111
1001001010011
1000010000011

Octal 2 digits (low bits first):
Unsorted crib sheet for above:
72 is 2h-7d-6d-As-5h-9s
35 is 7d-6d-As-5h-9s-10d
52 is 6d-As-5h-9s-10d-2s
25 is As-5h-9s-10d-2s-Qh
...
will finish above later
note that 111010 translates to octal 72 (111 010)
note that 110101 translates to octal 35 (110 101)
note that 101010 translates to octal 52 (101 010)
note that 010101 translates to octal 25 (010 101)
and so on ...

Here's the whole thing:

The effect: The magician gets 6 spectators on stage in a horizontal row.
The magician "shuffles" a deck of cards and "cuts" deck a couple of times and hands deck to first spectator and the magician turns his back and instructs the first spectator:

"Cut the deck several times and then deal 6 cards in a row (one card to yourself and one to the 5 other people) and look at your cards and remember them and then hide the deck and the six cards".

The magician turns around and asks a few silly questions and then says "Concentrate on your card, I'm having trouble with the red cards, if your card is a heart or diamond then close your eyes and concentrate extra hard".

The magician looks in his comical ESP book (or a secret crib sheet) and then names all six cards.

See below.
4C-2H-7D-3C-4H-6D-AS-5H-9S-2S-QH-3D-QC
8H-6S-5S-9H-KC-2D-JH-3S-8S-6H-10C-5D-KD
2C-3H-8D-5C-KS-JD-8C-10S-KH-JC-7S-10H-AD
4S-7H-4D-AC-9C-JS-QD-7C-QS-10D-6C-AH-9D

How to create this special P7 deck to do this trick:
Way ahead of performance time starting with above Tamariz deck:

1. move 3c-4h (pos 4-5) to after QC (after pos 13).
2. move 10d from pos 49 to after the 9s (after now pos 7).
3. move 3s-8s from now pos 22-23 to after 6c (after pos 50).
4. move the 4c (pos 1) to after the 8h (after pos 15).
5. move 2c (now pos 26) to after 4d (pos 41).
6. move 7s-10h (pos 35,36) to after 4s (pos 38).
Cut the 2h (one card) from the top to bottom (so you have a card different than the "tell tale" 9d and YOU know that this is NOT a pure Tamariz deck).

Result Tamariz P7 red card wrapping de Bruijn deck:
7d-6d-As-5h-9s-10d-2s-Qh-3d-Qc-3c-4h-8h
4c-6s-5s-9h-Kc-2d-Jh-6h-10c-5d-Kd-3h-8d
5c-Ks-Jd-8c-10s-Kh-Jc-Ad-4s-7s-10h-7h-4d
2c-Ac-9c-Js-Qd-7c-Qs-6c-3s-8s-Ah-9d-2h

Note that you can NOT use this deck to do the Tamariz effects but you can do this Leo Boudreau's "Eyes Closed if Red Card" trick!
Also it is easy to restore this deck back to Tamariz.

Left two digits are octal (low bits first) first digit is 0-7. The second digit is also 0-7:
Sorted crib sheet for Tamariz full 52 P7 deck (hearts and diamonds are de Bruijn "1" therefore if you know where the "1"s are among the six chosen cards then you can easily mentally construct the two digit octal code and look at the below crib sheet to know identity of all 6 chosen cards).

Example:
Spectator 1: eyes closed (binary "1")
Spectator 2: eyes closed (binary "1")
Spectator 3: eyes open (binary "0")

Spectator 4: eyes closed (binary "1")
Spectator 5: eyes open (binary "0")
Spectator 6: eyes closed (binary "1")

Therefore:
the first three spectators are indicating 110 which is octal 3
the second three spectators are indicating 101 which is octal 5

You (the magician) look up code "35" below and you know that the six spectators have: 7d-6d-As-5h-9s-10d

To restore this P7 deck back to pure Tamariz:
Restore the 2h from bottom of deck to top.
Restore 7s-10h to after Jc
Restore 2c to after Kd
Restore 4c to top of deck
Restore 3s-8s to after Jh
Restore 10d to after Qs
Restore 3c-4h to after 7d
Now you are back to pure Tamariz.
