Mystery solved

I've been carrying a big mystery for a long, long time. Today I finally saw something that made everything fall in its place!



In the central staircase in the office building I worked in on the Scopus project, on one of the glass windows the following cryptical message was written:

AKAR KITTEN

Who or what is an Akar Kitten..? Are those cute or extremely dangerous..?!



But today, on my way home, I saw this white van parked beside the road:

'Kitten' is Dutch for applying lute or sealant...

So my elusive Akar kitten is nothing more than a company that applies sealant...

[ if I ever need some sealant, I now know who to call... ]
