Alright, I saw the contest, I was eating grapes, and there was a knife on my desk. Grape o' lanterns ensued.
Initally, I put red LEDs into them, and the overall effect was pretty neat, especially considering that grapeskin is thin and veiny. Since I had half a dozen or so of these, though, I decided to go bigger. Behold the grape vine:
It looks exactly like normal Xmas lights at this distance, true, but each one is a unique little grape o' lantern. Of all the faces I made, most of them were pretty generic, but two were neat enough that I took pictures before I ate them. Unfortunately, I couldn't really get a decent close-up photo, so it's imagination time.
This one is my absolute favourite. It just turned out so well with the red LED that I wish I had a photo that could do it justice.
You can't see the face, but you're not missing much. I like this one just because nothing says halloween like a head on a pike. It also reminded me that in the miniature fruit community, sugary girl drinks probably look like Vlad the Impaler's courtyard.
