This is really cool looking but I don't know how safe it would be. I could just see someone not knowing these steps are different in the dark and hits the uneven slope or steps. Then someone in a wheel chair might not navigate the slope properly and end up going down the steps instead. The pattern is still really cool to look at. Ideally there would be a flood light to the left of this photos vantage point to shine an even light on the steps so they're visible at night.
