I found them on Google Images. They are .png files.
I sized them Adobe Photo Shop to 124x124.
Create a file called ICONS. Drop into your phone system under pictures.
Using Nova Launcher you can then change the icons.
If you want them to appear on your lock screen you have to change out the icons in HTC Sense first.
You can do this using a program called Desktop Visualizer from the Play Store.
