The idea came from a Chinese gadget---a magic liqueur cup with a small pornographic photo at the bottom; when the cup is empty, you see nothing but when it's filled with liqueur, you see an 'exciting' image. It is a
small play with desire and appetite.

For the "Magic Sake-cup for eternal swimmers" instead of a kitsch photo, you'll find a small swimmer at the bottom of the cup.

This new cup itself is a small container, like an airplane, like the space we create during the "swimming". The swimmer is eternally there but it only appears when the container is FILLED...filled with thought, filled with
music, filled with pleasant liquid (sake, wine, liqueur, water, even maybe coca-cola).

Or...
it's a small TV to look at the thing you forget to see.
Meeting with your inner bottom.

Pour into cup, drink, and repeat as necessary to meet the eternal swimmer!
Enjoy your sunset breakfast with this magic cup!
