SLIP CITY

A night in Halcyon: trails of light from crowds heading for four stages, signs at the corners

You can't move anyone. You can only tell them where to go.

Each night, a city throws a festival. Crowds pour in through the gates, each person heading for a stage, and nobody knows the way: they read your signs. Place arrow posts, totems, gantries and floor strips, and watch the trails of light find their stage as the music builds.

On iPad and Mac. Free to start; one purchase, the Full Festival, opens every city and town. No ads, no tracking, nothing collected.
