You know someone who is a photo-bug? Photo JoJo store has some really cool gifts for the photo gadget lover, or just the lover of photography. My favorites include: The elastic Macro Lens band for phones, lens screw-on adapters for both fish-eye (0.35x) and telephoto (2x) zoom, and 90 degree "Super secret spy lens" for seeing around corners, or just taking pictures sideways.
Check these, and the other gift ideas out--and don't forget your favorite Professor! (Even if it isn't me!)
