DALLAS (CBSDFW.COM) – The Dallas Mavericks are celebrating all things Dirk Nowitzki over the next week as the legendary player wraps up his 21st season in Dallas.

Many fans, players and coaches around the NBA suspect Nowitzki will retire after this season, although he hasn’t said so himself.

Throughout the season, fans in other NBA cities have paused to give Nowitzki standing ovations in what they believed would be their final time to see him play.

Here’s what’s happening in downtown and the American Airlines Center:

41.21.1. AUGMENTED REALITY WALL IN DOWNTOWN DALLAS

The back of the YMCA building (601 N Akard), which can be seen from the intersection of Field Street and Ross Avenue, has been taken over with an incredible 68’ x 193’ Dirk Nowitzki mural and augmented reality activation. Fans are directed to Mavs.com/AR to access instructions and once activated, Dirk comes to life with 21 shots from all 21 of his historic seasons.

The creative and technology studio Groove Jones produced the AR experience, with creative direction from the Dallas Mavericks, by taking both photo and video assets to bring the animation to life. The wallscape will be active through April 13th and fans are encouraged to share their experiences through social media using the hashtag #mavsAR.
