354c is the PMS colour of the green needed to make
green
screens as used in film and photography for special
effects.
The idea is to provide in a public place a large
physical block of this exact colour, that has an 'infinity
coved' bottom where it meets the ground.
This means that people
can pose in front of the green
screen and use the results to easily transpose themselves
unto different backgrounds.
The ground area of the curve where people stand will
need regular cleaning, as it may get dirty from feet etc,
but a donation box should be able to collect enough
funds
to maintain the screen. A combination of carefully
positioned lighting ensures that the screen is always
shadowless and usable even after dark.
Users can be invited to post their results to a website.
