It's a Bird! It's a Plane! It's a Castle in Spain! Super Chain.

Twenty-nine inches of chain, joined into a loop, dropped onto a flat surface, forms an endless variety of pictures, patterns, designs etc.

This one is on the kitchen table.  It can be used in restaurants,  while travelling,   as a performance art show,  at parties ...

Simple, portable, creative, fun.

Another option is to use finger as 'pencil' with the chain as the 'lead'.
