Hello
The first picture you linked is the Slide to Unlock (SU2U) app. it has been modified to include a custom slider (the HTC logo that you slide left to right to unlock the phone) as well as a custom HTC background and Clock pack.
A simple search of just site alone resulted in some threads you can use as well as the person that came up with the program over at XDA's site

Its unfortunate but he has suspended all work on the SU2U app as well as S2P(Slide to Play) and S2V(Slide to View) apps as too many people were charging for his software in package deals and not crediting him or paying him as well
Those links should get you started in the right direction to either create your own look or download the parts or packages to make it as you want
