I just discovered the official website has a neat puzzle game. You get rewarded with a high quality version of an event CG from the actual game, for different desktop resolutions (wallpapers).
Just click on one of the images and go for it, entertaining if you're bored or something =)
That's a direct link to a subpage though because the site is in Japanese. The main site is obviously http://www.fandc.co.jp/canvas2/
(note: one or 2 adult images are on it so you must be over 18. No adult images on the puzzle page though)
Anyway this game has very pretty artwork... I knew of Canvas before Canvas 2. And it also has pretty artwork.
I reccomend you download the promotional video on that site by the way (or the "trial" demo if you like). The video is really nice and the song is great, it has no adult images by the way.
Don't know if the trial has any adult content, never got it to work.
Actually, speaking of songs, the reason I was scouring the website was because I was looking to see if this game has a soundtrack released yet. Incidentally, anyone know? I don't think the first Canvas game got a soundtrack release unless it's just gone into obscurity... I hope they do release one. Oh well...
