Levi’s is presenting a series of limited-edition T-shirts, designed by Brazilian-born artist and activist Vik Muniz, renowned designers The Campana Brothers, visual artist Mark Bradford, and director Carlos Saldanha. The first of them arranges workshops at the Rio de Janeiro arts and technology school, Spectaculu, where he provides in insight into how visual arts and technology are blending together to deliver stunning results. The new Levi’s tees line titled “Friends of Vik Muniz for Spectaculu” features impressive designs, which are a way more that a tees pattern—they work as real pieces of art and evoke strong emotions in those who can feel other people’s pain and joy, despair and creative mood.

YouTube has introduced its newest tool, Campaigns, for non-profits, which helps create online initiatives aimed at raising awareness and increasing the number of views or subscribers, and track the progress of the initiative.

Microsoft has released a campaign to promote its upcoming tablet Surface, which is to be available to purchase next week. The new promotion has arrived just in time for the launch of the pre-Christmas advertising season, thus encouraging more consumers to buy Surface tablets as gifts to their loved ones (though, the adverts do not relate to the hottest shopping season directly). With this move, the tech giant is definitely enters the battle with its major competitors, Amazon, Google and Apple, which also have something to offer.
