Try to guess what “Mantra” is just from the landing page of the website

One of the icons is copied from the old iOS Game Center icon. Maybe they got it from this package: http://www.iconarchive.com/show/ios7-style-metro-ui-icons-by...

Spoiler: Mantra is a collection of free and open source tools integrated into a web browser, which can become handy for penetration testers, web application developers, security professionals -- https://sourceforge.net/projects/getmantra/

No idea whatsoever!
