'''Logon System''' was a french demo group wich was very famous due to really great demos and new techniques the coders at Logon used. While [[The Demo]] was for a very long time the best megademo ever released on the CPC, [[Overflow]]'s demo III was one of the most extreme hardware demo ever produced.
