I'm so glad you like everything. I'll admit, I didn't even think about belly dance accessories with the purse organizers, but that is AWESOME!
As for the microscope slide pendant, it's made of microscope slides, with the picture in the middle of two of them. I'm really glad you like it, as that is really the best theme ever!
(p.s. the tiny canvas bag is also a BSG nod. I didn't fit much in in the way of sci-fi nerdiness, which we share, but I got that little reference where I could!
