I’m proud to present you my first Xposed module (and in general my first ever released app): LockMod.
This module allows you to modify your lockscreen and do some crazy stuff with it, for example change the colors and sizes of your pattern, change some timings and even choose between 3 rainbow shaders! Additionally, you can change several timing options and set different animation interpolators.
Because this is an Xposed module, you’ll need the Xposed framework installed for it to work. More information can be found in the support thread.
