This CK is inspired by the work of H.R. Giger, the mastermind behind the design and visual effects in the movie ALIEN. By popular demand, I have decided to release a red version on Cydia. Be sure to check out the normal green version as well! Using a total of 108 keyboard images, every possible layout is perfectly themed including all Default/Emoji/Siri setups, all NumberPads, and Siri Dictation.
The font used in this theme is "Alien Extended Font" which is also available in Cydia.
Many thanks to Yoo Seung Kim for creating ColorKeyboard, and to PhatMartino for helping me out with a few things
