muito bem sacado e útil esse post: ao invés de criar ícones em diferentes tamanos (16x16, 64x64, 128x128...), que tal usar Deep Zoom?

A major pain when creating high-quality icons for various different sizes is not that the icon designer has to deal with multiple raster images to support different output sizes – it is the fact that the designer needs to create, manually grid fit and maintain each of these image variants separately, which can result in a lot of tedious work (as silly redundancy always does), especially when late changes need to be applied.
