Shark Hologram LED Night Light Lamp
If they'd given Joseph an Amazing Technicolor Dream Shark instead of a Dream Coat, this holographic LED lamp is probably what it would have looked like. It would've been a way better gift too--I bet Joseph's brothers wouldn't have messed with him or, like, sold him into slavery if he'd had a Roy G Biv shark watching his back.
The LED shark is a flat acrylic plate of a lamp whose lined design gives it a 3D holographic look. It comes with a remote that flicks it, fins to fangs, through neon displays of purple, blue, green, cyan, yellow, red, pink, and white.
