Most of you guys voted yes for a monthly themed spot look change,link.And here is the forum topic to post all the theme/motto/icon/banner suggestions.

It goes like that:

-suggesting themes; [for example certain magazine shoots, award shows, concerts, music videos etc.] Everyone can suggest 2 themes per month
[at the end of the month]
-then a pick with the themes at the beginning of the month, vote for your favorite
-submit banners until a set deadline
-another pick is made with the banners
-the banner maker whose banner won makes few icons with the same coloring as the winning banner in order to achieve a matching spot look
-another pick is made for the icon
-ask one of the F4 to change our spot look
-and this every second month

Hope it's all clear, if not ask in the comments plz :)
