I got the idea from looking at tinted windows; basically the idea is that they are regular sized plastic playing cards, with all the regular values and everything, however, turn them around and they are clear!
||Any notions as to how these could be made?
||Could they bend (& thus be shuffled as normal?)
||You could make them out of clear tinted plastic. Print a load of evenly spaced dots on one side, with the dots coloured black for the back-ground and (say) red for the pattern / number / suit. Choose a tint such that the red / black dots all look black from the back.
||Not possible, for thermodynamic reasons.
||Tinted windows on cars work because
the inside is in relative darkness
compared to the outside. Tinted glass is
shiny so when the light is cut down (in
both directions) the features seen in
reflection overwhelm whose seen in
transmission allowing the contents of
the car to remain private. There is no
magic ingredient that stops what
happens inside from being seen outside
||That said, clear cards are already
available. They have identical patches of
opaque ink printed on a base of scetate
or similar material. On this opaque
patch, the value of the card is printed.
||I like TLAOB's variant of using evenly
spaced dots (often used for oneway
transparent signage on windows) to
the whole card effectively seethrough.
[+], for this, even though I think the
poster has misunderstood how tinted
||You're right, I have no idea how tinted windows work, I just said thats where I got the idea from, not necesarily how they would work. But thanks for enlightening me.
