What to do with left over tiles?

We've got around 150-200 of these tiles left over that were used from our toe line on the steps. I was trying to think of something creative to do with them. The builder says the plaster guys can put them in the pool if we want, but nothing really comes to mind to do with that many uniform tiles. Any ideas?

Keep them in a safe place for the day that you need to replace some tiles. The style may become unavailable and you'll have some to do any future replacements.

cover a table with therm for around the pool. I used left over tile from my kitchen remodel to cover my BBQ island .
