Hey guys,
I'm really at a loss of where to begin even making something like this myself, and I really have no concept of how much work it would take to do, so excuse me if I'm crossing any lines.
Basically, I want to make a clock theme that works with winterboard...I don't know if it's maybe possible to edit the HTC one or something into what I want, so let me know if it's possible!
I just want it to be a clock like that on the lockscreen on the iphone but in blank position you can see on my screen below:

Any help anyone can provide with this would be great. Really don't know where to start. If someone already has something like this that they've made, that'd be great too!

tl;dr, I need help making a theme

Thanks in advance guys!
