@SimoAmi:
Those icons are definitely very professional-looking, but aren't they a bit big? I mean, I don't intend running my system at 2048x1536 all the time...
Not an issue really! This guy can design icons in any given size. Take a look:
http://everaldo.com/splashs/sigma.htmlAlso, in windows and mac systems, icons are stored in different sizes and color depths in the same file. e.g. 16x16/32x32/64x64.
That makes me think, why not have an upgraded icon file structure, with same file extension and backward compatiblity !!
