How would you like a greenhouse that’s powered by the USB port on your computer? only $15 at computergeeks.com. Sorry Mac users, it requires Pentium III 1.5 GHz processor or higher. “It comes with a computer interface that monitors growth rate, and includes calendar, wallpaper and bookmark settings so you can grow and care for your own desktop plants.” It comes with Marigold seeds. Marigold flowers are kinda white trash.
I own an aquarium with plastic fish that’s run by USB. It’s not hooked up cuz the motor that activates the plastic fish is quite loud.
