Lightbulb? Candle?

Depending on what you see... this could be a lightbulb, or a candle.  Or even a hot air balloon.  This piece was created as a result of the off-cut from another design and rather than put it in the scrap bucket, I made it into an ornament. 
 
(although difficult to tell from the photos, this glass is a yellow and white whispy glass)
