1st Logo (2006-2013)
Logo: A swirling cloud of particles comes from the right and forms the blue condensed circle made of several internal circles. The thing moves right and creates the word "kalypso" in white, attaching to the end as the letter "O". The word shines weakly.

Technique: Computer animation.

Audio: A creepy synthesized soundtrack with a 303-ish sawtooth bass when the company name flashes.

Availability: Seen on a variety of games, including Tropico 3, Patrician IV, Imperium Romanum and Ceville. Kalypso has a lot of games published in Europe, so this logo is not hard to find.

2nd Logo (May 23, 2014-May 30, 2017)
Logo: The letter "O" from the previous logo rotates and swirls in mid-air, finally setting among the other letters and forming the logo.

Technique: 3D CGI.

Audio: A wind and xylophone soundtrack.

Availability: Seen only on Tropico 5 and its expansion.
