Very cool video/demo of Linux desktop special effects . . on “top-shelf” equipment (newer PC’s (since 2010 or newer with nvidia or intel iris-pro graphics). None of these effects are available for older, basic and bargain-basement PC’s.
NOTE: the language is Hellenic (Greek) but for the demo, it’s not needed to understand the audio (more & English vids are available if interested).
OK . . . see video below this one for an English version . . .
