Frequently Asked Questions

Impossible Corners are a series of three designs that when placed in the corner of your room create the illusion of geometric shapes that move and shift with you as you move around the space. Each is made of three precisely designed sections: two wall pieces and one ceiling piece — that when combined, invert your perception of space.

Follow our installation video for easy instructions. Preparing your walls ahead of installation is key to keeping your Impossible Corner as sticky as possible.

Impossible Corners work best on smooth, painted surfaces. The adhesive is repositionable and won't damage your walls. Not recommended for heavy texture or popcorn ceilings. We cannot accept returns from products that have been peeled and attempted — please contact us if you are unsure if it will work for you.

Furthermore, your corner must be at 90º right angles — no crown molding or trims will work with the decal setup.

Designed to be removable and repositionable. The gentle adhesive peels cleanly from most painted surfaces. Results may vary by wall type — we recommend testing in an inconspicuous spot first.

Unopened kits can be returned within 30 days for a full refund. Once the vinyl is peeled, it can't be resold and isn't eligible for return. See our full Shipping & Returns policy.

Incredibly quiet — around 30dB. And yes, please touch it! You'll feel the secret your eyes can't see — the objects vibrate 80 times per second. The electromagnet is low voltage and safe for all ages.

We make no medical guarantees, but most photosensitive epilepsy is triggered at 5–30 flashes per second. Slow Dance runs at ~80 flashes per second, which is typically imperceptible. We have had some reports of more sensitive individuals sensing the strobes in Slow Dance, so consult your doctor if you have any history.

The effect weakens in bright ambient light. It works for most indoor environments, but direct sunlight reduces the effect significantly.

Light objects that vibrate well: feathers, plants, flowers. Think of it like a vase — the contents are temporary but beautiful. Feathers last indefinitely; flowers last a day or so.

1 year limited warranty covering manufacturer defects. Contact us within the warranty period to request repair or replacement. 30 day return policy for unpeeled packaged product only.

The strobe can cause flicker on video. Adjust your camera's shutter speed or use Syncro Scan / Clear Scan if available. Play with the brightness on smartphones, as sometimes this lets the camera better sync the strobes. For TTL cameras, you can sync to the strobe output.
