Real Aquarium HD for Mac1.2

This APP is so beautiful I just can't stop looking and listening. My kids are crazy about it and it actually helps them with their homework. Its going around our school like hotcakes. It works totally fine on my mac. Bravo John H, keep them coming!

Granted it looks nice. And thanks to the developer for offering it free (for a very short time) so we could appreciate the quality of his work. However, once installed, this app takes a huge 2,26 GB of space! Twice the size of the full edition of Microsoft Office for Mac 2011, more than 3 times Apple's iWork '09 and much more than the 5 Apple iLife apps combined! Just to watch some sea creatures on a kind of electronic new age music... Also, there is no mention of the source of the undersea clips or who are the composers of the music (and if you look in the app package content, you'll discover some music tracks from the well-known commercial video game 'World of Goo' - in there you'll also find a couple of tracks from the Razordoll album 'Dysnomia', an obscure Hungarian rock band). Are the video clips and music tracks in the public domain? Or was the music composed and the clips shot by John H. Meyer himself, the 16 years old developer of Real Aquarium HD? I simply wonder because the 'Animal info' that explains the species has been cut and pasted directly from Wikipedia...
