Seco, an Italian company, specialized in Embedded Systems development has developed a light bulb with a pico projector (DLP) that replaces your light bulb and project videos/pictures or anything you can think of on your wall.
The product is supposedly 99% made with Texas Instruments chipsets, mainly Texas Instruments OMAP3530 processor (ARM Cortex A8) and it runs Android, WiFi, Bluetooth, inside a lamp. The maximum power consumption is 25 W (green bulb maximum power consumption). This is currently a prototype and could cost between 200 and 400 USD retail. A microphone and speaker is also available, so it could possibly be used with Skype. Have a look this really seems promising. Soon we may also ask: “What OS are you running in your light bulb ?”
