Stained Glass explained in fewer than 140 characters

 How would you describe stained glass in less than 140 characters?

Color dancing (like this but to vague)

A rainbow hanging in your window

expensive (negative)

investment

heirloom

religious decoration

Colored glass material that lets light through and also the art made from that colored glass (this one says it to me)

Remember to keep art in your heART,
