It does look really really nice, but I don't get why the appcenter has to be represented by a shopping bag – it really doesn't scale well down to 16px (I know I know, 16px is quite gone from gnome-shell, but still I liked that criterion for icon-drawing...)
Hehe. A bit of background: this was done as a rebound to an actual WIP that used this metaphor and I didn't want to change it. Also, I've explored other metaphors and all of them don't fit and over-used.
Also, check the discussion on the original post. I didn't give it that much thought so I don't have an opinion about the matter.
Ooops, seems I tripped into the shopping-bag trap Sorry about that and nice-looking bag you created there! Nice how you tried to take the edge out of the whole market/money/free-as-in-beer discussion with the present/package (at least that's how I read it).
What are your thoughts on a linen shopping bag by the way?
It's okay. As you've seen the discussion had every sort of point-of-view.
That wasn't totally my intention when I used the 'present' icon, but it was not not my intention too.
As for the linen bag, you may use it to mean the icon/bag/logo/brand/software is durable, personal, familiar vs. plastic, to give away, has this dude's logo printed on it... . But it's almost 1 AM and that's as far as I can go.
