It's Dark In Here....Lumos!

I've seen cute maternity tees (No I'm not pregnant, I was just browsing, no one get excited) that illustrate things the fetus may be doing in there...and this idea sprang into my head, hope you like it!  Oh and I will probably offer this on tshirts and maybe expand to some other geeky fetal images, so if you're reading this and would like to comment I'm interested in knowing whether people like cafepress, zazzle or spreadshirt best.  Also, if you'd like to suggest geeky things go for it. ;P
