I found this on the 3rd page of the Droid Incredible themes area on xda, and it works on SD builds AND on NAND builds for our HD2 Sense ROMs as well as other phones running Android from NAND or SD (as long as it's sense). Basically a bunch of cool animated flip clocks and some non-animated ones.
Because the DHD ROMs seem to be slower and buggier than Desire based regular Sense ROMs, I wanted an animated flip clock on my regular Sense ROM on SD and this works beautifully.
Full credit to the OP in the linked thread, I'm just trying to provide the info.
3D HD flip clocks & non flip clocks for all roms! 4x5 also available for non flip!! - xda-developers
INSTRUCTIONS
For NAND ROMs just flash the zip via CWM
For SD ROMs you have to extract the zip, you will end up with 2 folders. In your Android folder on SD (whatever the folder is called that your Sense ROM is in) create a folder called "root" if there is not one already. Move the 2 folders into that root folder and soft-reset your ROM and you are good to go.
