Let's face it: There's always a part of us that can't resist a good bit of pixel art -- be it on bank notes, in games or even in the form of sculptures. For those who are seeking something more interactive, you may want to check out the Dotti by Hong Kong startup Witti. What we have here is a little eight-by-eight LED block with Bluetooth radio and a battery -- up to 720 hours on standby or 5 hours of continuous display. When paired with its iOS or Android app, Dotti serves as a pixel art canvas (you'll be able to upload your own work), a clock, an icon-based notification display (for calls, e-mails, text, calendar, popular social networks and more), a music visualizer and even a virtual dice. Simply swipe along the top side of Dotti to toggle between these modes, as shown in our video after the break. Want one? It'll arrive just before the holidays for $99.
