These are really creative, but I'm a little concerned that that 2 and R don't read clearly. We also would really like to incorporate a butterfly somehow since it represents personal transformation and spiritual growth. Can you also play with different font types and a light/dark green color scheme?
I like the lotus idea! #60 - The only thing I worry about it the printing and it being 3D. Can you play with the dimensions a little to make it printer friendly?
