"When I read about the challenge it got me thinking about night and day. I flipped around a couple of ideas. Everyone knows about the Day of the Dead, so I thought about Night of the Dead. Making the lightbulb fill with a glow in the dark sugar skull, which would look rad under blacklight. At night moths flock around lightbulbs, so I thought what if butterflies were attracted to lightbulbs in the day time. I guess this could also work the other way around too "Día de Muertos", with the sugar skull showing up in UV ink, the butterfly in glow ink."
I was pretty pleased with the way it came out, so wanted to put it up here.
Thanks for looking!
