i am bored from using of random images as my descktop wallpapers
if you noticed in windows seven they used some paintings that automatically changes in a time interval , although i don't know what is the name of those paintings style ...
anyway if you painted something that you use it for your own pc please share it with us tooso that we can use it ?
personally i believe a wallpaper must be colorful and juicy in a way that is fair for eyes ... but my knowledge on colors is very low and i can't discuss anymore
also i tried to find some example but unfortunately they are very rare and this is the only thing that i found : ( i guess the 1280x800 is an ideal size for most of laptops )
cheers
