Archimedes Laboratory

Archimedes Laboratory
has added new pages on mechanical puzzles. (visit: http://www.archimedes-lab.org/workshoptangram.html ) Puzzles
with ‘vanish’ effects are a curious branch
of geometric pattern puzzles (mechanical puzzles) which
is useful for hands-on teaching ...purposes and as math-thinking
motivator. A “vanish puzzle” is
actually an optical illusion that can be used in mathematics
classes to help students reason about geometrical figures.
When the pieces of a vanish puzzle are rearranged,
part of the original area seems to disappear, even
though the outline of the puzzle shape remains apparently
the same!
We invite you also to visit the updated pages on the Tangram puzzle:

Archimedes Laboratory challenges your creative visualization with "droodles".
A "droodle" puzzle is a kind of minimal cartoon featuring rather abstract pictorial elements accompanied by an implicit question: "What is it?". Droodles are based on the 'pareidolia', an innate human tendency to impose a pattern on random or ambiguous shapes...
