My 8th graders are creating anamorphic art right now - I use it to push
their proportional reasoning skills past just the grid enlargement
Each year they do a large self portrait from a photo - we prepare by
doing several anamorphic (distorted) grids - including the type Mr.
Beever uses (stretched out - not the technical term... but you know what
I mean - you can see it on the photo of the woman in the pool... there
is a photo where you can see the stretched out leg.) We also use
reflective cylinders with grids - they make great watercolors. I have
the info on cones and anamorphic art - but they are a challenge.
Ted Rand illustrated a Sandburg poem for an anamorphic book - called
Anno has an anamorphic alphabet
There is a book 'Hidden Pictures' that has a little info -
I think all are out of print - be careful where you get your images to
share - most was created for entertainment - and some are adult
