This image was created as a replacement for File:Portal icon.svg. However, it is not a derivative work, as it was created entirely from scratch. The only elements that it shares with File:Portal icon.svg (horizontal blue puzzle piece with keyhole) are so simple that they are not protectible by copyright. Whatever minor creative features that are copyrightable in File:Portal icon.svg are done quite differently in this version.
