Yin Yang 彩虹製造器

The vinyl is surprisingly durable—it hasn't peeled at all after a week of direct sun. My kitchen now has tiny rainbows dancing on the counter every afternoon, exactly as promised.

I stuck this on a south-facing window and within seconds tiny rainbows were bouncing all over my kitchen walls. The vinyl itself is surprisingly clear and unobtrusive when the sun isn't hitting it. Definitely brightens up an otherwise gloomy corner.

I wasn't sure the vinyl would stick well, but it's been on my kitchen window for a week without peeling. The rainbows are vivid and appear exactly as described when the sun hits it. My cat loves watching the light show on the floor.
