+FlashPrance
+===========
+
+FlashPrance is a toolkit allowing data to be transferred by flashing
+lights on and off.
+
+
+Application
+-----------
+
+It's primary purpose is to allow settings to be sent from a computer or
+cellphone to an embedded device, such as an Arduino.
+
+The screen of the computer or cellphone will quickly flash between black
+and white at different intervals, and the device shall measure the
+duration of the light intervals to decode the data.
+
+Because bandwidth is limited by the frames per second that can be
+displayed on screen, it is only suitable for very small amounts of data.
+It takes roughly 1 second to transfer 1 byte.
+
+It's benefit is the cost and convenience. The sender (computer or
+cellphone) does not need any additional hardware or drivers - only the
+capability to flash an area of the screen - this may even be a web page.
+The only additional components on the receiver (embedded circuite) are a
+light sensor and a resistor - this should cost less than $1. 
+
+
