Glow in the dark interlocking floor tiles

At the RACV Australia Day Picnic and Federation Vehicle Display in Kings Domain, Melbourne I noticed the use of interlocking plastic tiles to protect the grass. The produce used was Pro-Floor , which appears similar to the tiles I was looking at using for classroom floors. I notice they even offer one type which glows in the dark. The idea isn't that you cover the whole floor with glow tiles, just mark out evacuation routes and the like.
