In fact, not a hedgehog, and not longer tiki-piki, but continues a series of light-musical instruments. This time the control is carried out by touching the touch keys on the built-in touchscreen. Each key is responsible for a strange sound and light reflex. The mirror body ruffles and reflects, the speaker cracks and flirts with the rib cage. We created this installation for "Porsche Impulse Night" brand event together with the guys from FGA and Louder. The hedgehog traveled to 6 cities with them and survived in the end.
