In short - yes, it looks like I make testing, fresh Sparky spins.
Means:
1. Debian installation.
2. Adding Debian contrib, non-free and deb-multimedia repos and public key
3. Adding Sparky repos and public key
4. Installing favorite desktop and apps on the top of Debian base.
5. Installing Sparky apps, wallpapers, theme, icons, etc.
That's all.
