Flip Postcard

What is it

A jigsaw, except finishing it isn’t the end. The pieces are dealt onto the table like cards and turned face-up one by one; when the last one clicks in, the seams heal into a single postcard, and then the card lifts, turns on its edge and settles back down — on the back, a handwritten message, a perforated stamp and a postmark dated today. Six presets to choose from (sunset, snow peaks, night city, a camp under the stars, a cherry-blossom path, hot-air balloons), or drop in a photo of your own and rewrite the message and signature however you like. Cut it into 6 / 12 / 24 / 48 pieces, and decide whether a faint copy of the picture sits in the frame as a guide — going without is the real thing. When it’s done you can save both sides as one PNG and send it to someone.

Highlights

• Real jigsaw edges: every tab and blank is generated at random, and pieces snap when they get close
• Playing-card feel: dealt and flipped, dimming as it turns edge-on, with a highlight sweeping across
• The back is a real postcard: handwritten message + perforated stamp + today’s postmark, all editable
• Six preset pictures or one of your own photos; save both sides as a single PNG
