A spike-ridden public seating area only becomes safe when users deposit coins.
Designer and photographer Fabian Brunsing has created a unique (although unfriendly) park bench that monetizes its sitting usage. The seat is riddled with painful-looking spikes that only go away when park-goers deposit coins (about 70 cents) into its slot. The array of spikes then retract into small holes, rendering it a safe area to temporarily sit. The bench sounds a loud buzzer shortly before warning sitters that the allotted time is running out, and spikes will soon resurface.
