@d7mcfc, thx.

I have used phisical sky+sun and I played a bit with turbidity and water for having a plain blue. material are quite simple, mostly 2bdsf, jdhill AGS for glass (thx mate!:) ), and a micropierced aluminium with wheightmapped trasparency, though it is not visible here mostly because of the angle.
SL 12.73, 15h, 1400*1000 (vaio notebook p4 3ghz, 512 Mb ram)

@CJElven, thx to you too. I have to agree about the chair, but maybe a tiny bit of roughness or anysotropy might be needed, but I don't want to rework the chair again. thx again. I am changing the dates in order to have it less confusing.... cheers.
