I know Vidrepur (sp?) makes commercially available glow tile. Never used it. Came close though.

There are glow in the dark glazes, a craft store nearby has those. They have DIY sessions, you can glaze blank tiles, they fire them, then it's yours. I've seen glow in the dark done that way in person, it's pretty neat.

Laticrete makes glow in the dark grout. I've used that in a bathroom on a raised curb. Looks "normal" when the lights are one, but glows when dark. That was done as an anti toe stubber. Looked pretty neat as well.

That would be hot! There's been some creative and out of the box features in homebuilds throughout the years, that would be over the top. Jerry would be proud!
