On first inspection it appears to be a sequence of logic puzzles... I'm probably right but there is one very confusing thing about where this data comes from...

IMO this keygen failed as a keygen on many levels. Firstly, there are 3 different valid passwords (somehow I managed to miss one of those). Secondly the first part of the serial is always the same if your registering name is long enough. Thirdly, the output goes where you type in the password. (WTF?) Without any kind of anti-debug or encryption, this keygenme is nothing but a maths test (and a fairly easy one at that if you know anything about maths). The only good thing about it was the music.

Well done TiGa !!

It looks i failed on ArcTan part (1st part of the serial) - math is a nightmare for me too :)

@haiklr: nice name fro this keygen me, hope to see new keygenme from you - but with less trigonometry :)
