Arsen:
Well, in the past I was using different nicknames (Koenig, Saar, Ean, La Sarde) but they existed very short (2-3 months)

I've been "Arsen" for 5 years.
Arsen is one of the elements used in laser production. I mean the laser used in optical storage drives (CD-ROM, DVD-ROM etc.) - Gal, Aluminium, Arsen (I hope I wrote it right

). I'm very interested in optical drives. I chose "Arsen", cause it sounds better

If it was my surname, it could match to a person who comes from scandinavia (Norway, Finland, Sweden...). I always liked Norway from his visual point of view (fjord).
That was enough to decide
