This is a retina compatible iOS 5 lockscreen clock that has the time displayed in binary, as well as beneath it in plain text. Accessible by tapping the gear icon in the upper-right corner is a settings panel where many aspects to the clock can be changed. The background and foreground colors can be selected from 10 different choices, and both the space between and blurriness of each binary digit can be adjusted. Both the text display of the time and 24 hour time can be toggled. To remove the default lockscreen clock, install the package "Lockscreen Clock Hide" by David Ashman. If you like this clock, please check out my other clocks such as "Neon LS Clock HD." Please buy, and I hope you enjoy!
