Why Thank you, Love your new sig too.
This sig has been made in After effects and Photoshop, Mostly after effect. Used a camera for the 3D/Distance effect and Particular plugin for the smokey/Fogginess. Rendered it as a .mov imported to Ps as frames, did a bit of color correction, size optimization and added a nice little border. I'll do a more detailed write up if you are still interested.
