Black hole diagrams aren't easy to tattoo, that much I am certain of. Number two on my brother @tudikas. Also, today marks 5 months since I started using a tattoo machine! It's funny when you find something you really enjoy doing and it feels like you've been at it for years.
In the story of Alice in Wonderland, Alice falls in a hole while chasing the rabbit. I would want it to be like this. It would be a black hole she falls into to get to the wonderland. I like it because when she falls it is very long and deep. She is spinning and it is looks a little disastrous.
