Hi Christopher,
I was trying to compile Program-sample.tex because I find the
transparent white frame over the grey background very nice to see for a
pure electronic pdf. In the same range, the vit Zyka font demo catalog
(http://typokvitek.com/stormcontext/) push hard the limit of those
transparent overlays that I'm still in quest to reproduce.

interesting document (maybe there should be a copy on the wiki)

not sure what you mean here ... the demo shows up ok here; (maybe it will look 
slightly better if the big two-chars are behind the text) ; the main thing to 
keep into mind with transparencies is that some versions of the reader mess up 
anti aliasing when transparencies are involved;

i took a quick look in the style -)

\expandafter\processcommalist\expandafter[\glyphset]\doglyph

==> processcommacommand[\glyphset]\doglyph

\expandafter\switchtobodyfont\expandafter[\the\bigInitSize]#1}%

==> \expanded{\switchtobodyfont[\the\bigInitSize]}

actually i think that the expanded is not even needed here

(best to use UpperCaseNames in order to prevent clashes)

Thanks to Patrick it is already on wiki:
   http://modules.contextgarden.net/stormfontsupport
There is also source code for the catalogue:

P.S. Sorry for a delay I was several days off.

  Sorry for not answering for such a long time.  Please try the 
following code:


\setupcolors[state=start]

\startuseMPgraphic{bgnd}
   StartPage;
   linear_shade(llcorner Page -- urcorner Page
                -- ulcorner Page -- cycle, 2,
                0.2[red,green], 0.8[red,green]);
   linear_shade(llcorner Page -- lrcorner Page
                -- urcorner Page -- cycle, 2,
                0.2[green,red], 0.8[green, red]);
   BoundPageAreas;
\stopuseMPgraphic

\defineoverlay[bgnd][\useMPgraphic{bgnd}]
\setupbackgrounds[page][background=bgnd]

\startuseMPgraphic{brighten}
   StartPage;
   fill Field[Text][Text] enlarged 2pt
     withcolor transparent(1, 0.5, white);
   BoundPageAreas;
\stopuseMPgraphic

\defineoverlay[brighten][\useMPgraphic{brighten}]

\setupbackgrounds[text][background=brighten,backgroundoffset=2pt]

\starttext

\input tufte

\stoptext


  I'm getting a displaced background this way (leaving the 
backgroundoffset out does not help), but I'm sure someone will be able 
to tell us the secret incantation to fix that.

  Strange thing is – I had tried that a while ago and the transparency 
was simply lost.  (Right now, the numbers must be different depending on 
whether you put the thing in front of an MP graphic or in front of a 
plain color background.)  If that happens to you, try putting both 
graphics into the same stack of backgrounds, as in

\setupbackgrounds[page][background={bgnd,brighten}]

As a last resort, you could of course join the code into one MP graphic.

That's because you operate on a page (btw, it's StartPage ... StopPage); 
In this case you can better use:

\startuseMPgraphic{brighten}
  fill OverlayBox enlarged 2pt
    withcolor transparent(1, 0.5, white);
\stopuseMPgraphic
