These small shades can turn any wine glass into a lamp. The shades, designed by Anke Rabba and Katrin Kuchenbecker of Germany, make a lamp of any wine glass and tealight.
Simply take the wine glass, light a tealight inside, and top it with the shade. Voila: instant romantic ambiance. Available from Poaa: about 20USD for 3.
We don't see much more detail on the website but we're guessing the shades have a special armature to fit them to a wineglass.
