As in Football (Soccer) where you can show a player the yellow or red
card, the idea is that we can use the same concept ...but with a new
twist.
Below are scanned copies of the 64 cards included in theCreative Whack Pack created by
Roger von Oech. Here you
can either use the cards for introspective
purposes, or maybe show other players a card. A phase two of this
concept might include a way to keep score, but then a conventional
wisdom factor would have to be built into the equation.
Along this same vein, Brian Eno and Peter Schmidt put together a card
set called Oblique
Strategies, which uses the concept of random selection as a source
of inspiration.
