Hi Ed, thanks.
I see you've a passion for tiles, and that's nice.
1) We like #225. It seems that there, if I'm not wrong, tiles communicate by talking to each other and are shaped like comics balloons. Even if it makes sense please make them just geometric shapes, I think the balloons have already been overly used for communication metaphors.
Still on #225 please make the font just a little bit thicker, dark gray with a coloured dot on i.
2) Please make a variation with tiles in brighter colors
3) And last, because of the variety and level of your other works I'd be very keen to see a fully different and original proposal from you !
Thanks a lot
Luca
