Glazier

A puzzle about light. You have only three colours of glass — red, yellow and blue — and every window asks for more: orange, green and purple where panes are laid over each other, and dark lead where all three meet. Drag each pane into place, turn it until it fits, and watch the window fire into light as each section is finished.

A hundred and thirty-two hand-built windows across eight buildings, from a hermit's cell that teaches the craft, by way of an abbey and a ruined basilica that is rebuilt around you as you restore it, to a cathedral, a minster and a great cathedral with rose windows glazed in hexagons. Walk through each church in 3D, where the sunlight through your windows follows the real time of day. A new window every day, the same for everybody. And a workshop to design windows of your own and send them to friends to restore.
