A soap bubble odyssey.

Home to a series of experiments with soap bubbles, Iridisfera is an ad‑free wallpaper app.

Made in lockdown.

After two years of global pandemic, we all worked out ways of maintaining balance while social distancing. The soap film is my window, an extension of vision over great expanses. My name is Bogdan Chesaru. I made Iridisfera so you can wander with me.

An appful of patterns.

Explore the unaltered fabric of Nature. Form, color and motion in their purest manifestation.

Ad-free.

Some patterns are red,
Others are blue;
All are ad-free,
And so will be you.

Thin-film interference.

A soap film is a thin layer of water bounded by two layers of surfactant molecules. The iridescent colors arise from the interference of light waves reflecting off the front and back surfaces of the film. This natural phenomenon is known as thin-film interference.
