We love large displays, and the following version described by Instructables member kenyer is quite original and useful once constructed. They wanted some very large 7-segment displays, and instead of using a commercial product - created their own with a 3D printer which allows for the segments to be displayed with groups of LEDs.
This allows for a large, bright display which is also controlled with a simple Android app that communicates between the display and Android device via a serial/Bluetooth link. A perfect method of control once the display has been mounted for normal use. A quick demonstration of the display is shown in the following video:

Need a large, Arduino-compatible display - but don't want to make your own from scratch? Then check out our Freetronics Dot Matrix Displays. They're simple to use, yet very bright for indoor and outdoor situations. Available in various colours, the 32 x 16 LED matrix can display text and graphics quite easily - and can be daisy-chained together for extended displays.
