Sunshine Regenbogenmacher

I stuck this to my office window and now my desk is covered in tiny rainbows every afternoon. The vinyl itself is thin and transparent so it doesn't block the view at all. Definitely brightens up a boring workday.

Stuck it on my bedroom window this morning and by noon the whole wall was covered in little rainbows. The vinyl is thin enough that you barely notice it's there, but the light refraction is honestly way stronger than I expected.

The refraction is surprisingly bright even on partly cloudy days, creating clear rainbows across my living room. It was a bit tricky to get it perfectly flat on the window without air bubbles, but the effect is totally worth the effort once the sun hits it.
