JR拥有世界上最大的美术馆。由于他的摄影拼贴技术，他的作品在全世界的墙上免费展出，吸引了那些通常不去博物馆的人的注意。

他于2004年在克利希-孟费奈及其周边地区发起了“28毫米项目”，并在中东继续开展了“面对面”(2007年)，在巴西和肯尼亚开展了“女性是英雄”(2008-2011年)，该纪录片于2010年戛纳电影节(评论家周)上亮相。

JR创造了“渗透艺术”。在他的拼贴活动中，当地社区参与了艺术创作，演员和观众之间没有舞台分隔。JR的匿名性和巨幅肖像没有任何解释，给他留下了一个议题与演员、表演者和路人相遇的自由空间，形成了他作品的本质。

2011年，他获得了泰德奖，这给了他一个发誓要改变世界的机会。他创立了Inside Out，这是一个国际性的参与性艺术项目，允许来自世界各地的人们接收他们的肖像印刷品，然后将其作为对一个想法、一个项目、一个行动的支持，并分享这种经历。

2014年，他与纽约市芭蕾舞团(New York City Ballet)合作，用舞蹈的语言讲述了他对克利希-孟费梅尔地区骚乱的描述。他创作了芭蕾短片《格罗夫斯》，由伍德基德、汉斯·季默和法瑞尔·威廉姆斯作曲，并在翠贝卡电影节上展出。

与此同时，JR在移民历史上的重要地点埃利斯岛的废弃医院工作，并与罗伯特·德尼罗一起制作了短片《埃利斯》。

2016年，JR受到卢浮宫的邀请，他用一种惊人的变形让卢浮宫的金字塔消失了。同年，在里约奥运会期间，他在整个城市创造了巨大的新雕塑装置，以强调运动姿态的美丽。

JR has the largest art gallery in the world. Thanks to his photographic collage technique， he exhibits his work free of charge on the walls of the whole world – attracting the attention of those who do not usually go to museums.

Originator of the 28 Millimeters Project which he started in and around Clichy-Montfermeil in 2004， continued in the Middle East with Face 2 Face (2007), in Brazil and Kenya for Women Are Heroes (2008-2011), the documentary for which was presented at the Cannes Film Festival in 2010 (Critics Week).

JR has created “Infiltrating art“. During his collage activities, the local communities take part in the act of artistic creation, with no stage separating actors from spectators. The anonymity of JR and the absence of any explanation accompanying his huge portraits leave him with a free space in which issues and actors, performers and passers-by meet, forming the essence of his work.

In 2011 he received the Ted Prize, giving him the opportunity to make a vow to change the world. He created Inside Out, an international participatory art project that allows people from around the world to receive a print of their portrait and then billboard it as support for an idea, a project, an action and share that experience.

In 2014, working with the New York City Ballet, he used the language of dance to tell his version of the riots in the Clichy-Montfermeil district. He created The Groves, a ballet and short film, the music for which was composed by Woodkid, Hans Zimmer and Pharrell Williams, and which was presented at the Tribeca Film Festival.

At the same time, JR worked in the abandoned hospital of Ellis Island, an important place in the history of immigration – and made the short film ELLIS, with Robert De Niro.

In 2016, JR was invited by the Louvre, whose pyramid he made disappear the with the help of an astonishing anamorphosis. The same year, during the Olympic Games in Rio, he created gigantic new sculptural installations throughout the city, to underline the beauty of the sporting gesture.
