Actually I just created that thread and detailed instructions on customizing or creating your crazy intro video. The project itself was entirely done by WiiCrazy, hes also on gbatemp, but Im not sure how active he is these days, but u can try contacting him via PM. If youre serious about enhancing the project, might I suggest USB support?
Awesome, thanks again. I noticed WiiCrazy (I.R.on) created the source notes too, I'll try and contact him. I could be wrong and it probably isn't that easy but I assume that adding usb support would be a case of replacing "PI_INTERNAL_SD" with "PI_USBSTORAGE" in the source when mounting, but I could be wrong, I'm very new to this. Hopefully WiiCrazy can guide me on that.
