Clipper, if you have a blacklight those really show off the glow and show ponies quite nicely. Especially if you are looking into the process of them for the wishes project.
Example:
Dang it! Now I need a blacklight.
Clipper, thanks for the glow-in-the-dark pic! I had no idea the dark squares would look so cool lit by the glowing circles...wowsie!
Do any less unique ponies have mixed glow in the dark and not glowing things in them so I can get one that does that?
