Can I put an HTC flip clock on the lock screen? I have an HTC One X and it has the typical HTC flip-clock/weather widget loud and proud on the home screen.

I don't really want it there because it's a bit bulky but it would be nice on the lock screen for when I'm just taking my phone out my pocket to check the time?  Is this possible?  I can find setting to customise the clock on the lock screen but, for some reason, the only clock that list doesn't include is the flip-clock I'm after!
Install WidgetLocker Lockscreen. It allows to add homescreen widgets on lockscreen.

Update:
HTC widgets can't be added to WidgetLocker, but third-party general widgets can be. So, install Beautiful Widgets app, first. It has exact HTC flip-clock alternative.
