Grindstone Entertainment Group

1st Logo (2010-2012?)
Logo: We zoom out on some kind of tunnel on a black background that reveals to be a grindstone, in form of an "O" which is grinding the letter "n", other letters form, which end up revealing the word "Grindstone", with "Grind" in an orange color and "Stone" in a grey color, with the white words "Entertainment Group" below. The grindstone stops grinding the "n", and after that, we see that it formed some kind of yellow spark.

Technique: CGI.

Audio: Sounds of the grindstone grinding are heard during the whole logo, which end in a "whoosh" sound when stops grinding the letter "n".

Availability: Seen on some DVD and theatrical releases by the company during that era.

2nd Logo (2012?-)
Logo: On a black background we see some sparks, illuminating the grindstone from the last logo grinding, again, the letter "n", the sparks illuminate more the background, revealing the 3D text "Grindstone Entertainment Group", the sparks then shine the whole background, finally revealing the whole logo, which looks exactly like the last one.

Variant: On the American DVD release of Wings, the logo is already formed and it is zooming in on a black background.

Technique: CGI.

Audio: Same as the 1st logo.

Availability: Seen on some DVD releases, and on Private Property.

Legacy: Same as the 1st logo.

3rd Logo (2014-)
Logo: On a black background, we see the normal Grindstone logo, but it is still and crudely drawn. the spark then glows and the whole logo shines.

Variant: Sometimes, the logo is still.

Technique: The shining.

Audio: None or the opening theme of the movie.

Availability: Seen on Grindstone's family-oriented releases, and releases from Simka Entertainment, except for Wings. Most recently spotted on films like Hedgehogs and Pinocchio: A True Story.
