The 3.2 gigapixel “Global Selfie”, was made the with 36,422 individual images.

German artist Robert Rickhoff re-interprets the idea of public space with humor through a series of digitally manipulated photographs in a project entitled “out of place”. Rickhoff augments scenes within a seemingly commonplace environment to depict impractical yet lighthearted situations – including a playground slippery dip facing towards a busy road to a speed bump placed in an unassuming residential street that is actually a daredevil ramp. the visualizations are subtle yet provocative, forcing the audience to look twice to notice the unusual setting infused with tongue-in-cheek wit.

“The Ainu (アイヌ?), also called Aynu, Aino (アイノ), and in historical texts Ezo (蝦夷), are indigenous people or groups in Japan and Russia. Historically they spoke the Ainu language and related varieties and lived in Hokkaidō, the Kuril Islands, and much of Sakhalin. Most of those who identify themselves as Ainu still live in this same region, though the exact number of living Ainu is unknown. This is due to ethnic issues in Japan resulting in those with Ainu backgrounds hiding their identities and confusion over mixed heritages. In Japan, because of intermarriage over many years with Japanese, the concept of a 'pure Ainu' ethnic group is no longer feasible. Official estimates of the population are of around 25,000, while the unofficial number is upwards of 200,000 people”. – Wkipedia
