Avi Greengart loves his gadgets and his passion for them carries over into religion. Customs change as time goes on and now the twenty-first century has given birth to the gadget-laden yarmulka. Mazel Tov!
Male Orthodox Jews wear yarmulkas (or, in Hebrew, a “kippah”) to show deference to God above us. Many Jews choose the specific fabric of the yarmulka to identify with specific religious or political sub-groups; I have chosen a design to identify with an iPod, a Treo, and a PSP. God help me.
Such things aren't all that unusual. I once saw a young child wearing a yarmulka decorated with colorful dinosaurs. Kind of a Jewassic Park motif, I'd say.
