Vexil allows you to modify the Lockscreen to your liking

  Vexil is a tweak what is to come released in the near future in Cydia, and with its help we can modify a lot of elements of the LockScreen of our iDevices. If you look at the images above, you will notice the settings menu of the tweak and they basically allow us to modify the graphic elements of the LockScreen, remove them or introduce other new things. We can hide the clock and display a text in its place, we can curve the graphic element of the clock, we can change the color of the unlock slider, we can add a delay effect, we can modify the tests in LockScreen and introduce others, we can hide the status bar, we can add an unlocking animation and the list goes on.

  Vexil is to be launched in the near future in Cydia, it is not yet known how much it will cost when it will be available, but as an idea it is more than interesting.
