Hi Koki, you poster is really nice :) However i have two remarks (i hope it's not too late)
1) It seems that there is an aliasing problem in the perspective transformation of the screenshot, you should use a better interpolation technique.
2) This is purely subjective, but i think that the calculator replicant is a bit confusing imho. People external from the project can, at best, be curious about it, at worse, think it's a rendering bug or a strange wallpaper :)
keep up the good work, alex
