 Due to the large canvas a lot of the guidelines discussed elsewhere in this document do not apply. What still stands is the use of colors, the perspective and lighting.

 * The 256x256 icon needs to be nice when scaled down to 64x64 (25% zoom), so, in inkscape, it's necessary to use a 1x1 pixels grid with major lines every 4. Lining up the main objects to the major lines of the grid will help making the icon less blurry when scaled down.
 
 * Text: the best trick we found (atm) for text in high resolution icons is to use the text tool to write something (lorem ipsum, funny things, nonsenses and so on:-)) using the Bitstream Vera Sans typeface with a 6pt size, trying to have the main bodies of the letters between two horizontal major grid lines, then we convert the text object to path and simplify (ctrl+l) 3 times. In case the text is not visible enough when scaling down overlaying the line with a very subtle rectangle 4px tall will help (see text-x-generic).

+* Outlines: To make the things stand out we darken the edges using various tecniques. Lapo's favourite is to group the all objects costituting the shape; copy, paste in place, ungroup and make the boolean union to obtain the silouhette  [ctrl+c, crtl+alt+v, ctrl+u, ctrl++]; copy again; set this path fill to none, set the stroke to from 0.5 to 2 pixels in a dark color (usaully black) and set blur from 1 to 2 points; group it with the previous group; paste in place and select the new group and the pasted path apply a clipping mask (the pasted path will be used as a clipping mask) [Object -> Clip -> Set]. Now you can edit do group editing with the clipping mask in place [ctrl+enter to "enter" the group]. You can play with various stroke width and color or gradients and with different blur settings.
