My new app, Zen Puzzle, is now available on the Play Store 🎉

The idea is very simple: an app designed to help you relax by doing jigsaw puzzles, with no rush and no pressure, just the pleasure of piecing an image together bit by bit.

The moon illuminates the night with a calm, steady light, whilst clouds drift slowly across the sky. In Japanese culture, gazing at the moon is a moment of contemplation, when time seems to slow down and every thought finds its place.

@TVanWelsenes Thanks! Well... not the most original idea, you know, but I'm confident I can put my own vision into this app.

This is amazing!

GPT image 2 on ChatGPT
Prompt:
Generate a "cat" character promotional poster with a straight main visual composition. Each poster uses the upper and lower hierarchy: the most recognizable head, face outline, mask or outer outline of the figure is the large visual subject, forming a highly recognizable silhouette main shape; the middle and lower part is arranged with the complete figure as the second subject, showing a stable standing or slight movement posture, forming the visual core of the picture.

Double exposure and collage narrative compositions inside and around the large outline, combining multiple scenes, images, small character relationships, auxiliary elements and environmental layers in clouds, ink, and whitening. The left and right side is equipped with an echoing side of the scene, which creates story tension and space changes. Link the main character, internal collage, and large outline above with a flow of clues across the screen to enhance integrity and vision guidance.

The overall picture retains a large area of whiteness, and the edge is stained with ink and virtual broken, creating a real relationship and breath in the Oriental aesthetics. Overall style uniform, advanced and restrained, emphasizing layers, narrative, main visual impact and serialized poster language. Size: 3:4

Make the aspect ratio 3:4

@BatsouElef It's the mechanic of jigsaw puzzles. You have to move each piece in its spot, and when a piece is placed correcly, you can hear a pleasant audio feedback.
