materials challenge the traditional process-oriented notion of the craft medium by incorporating performance, interactivity and politics." The gallery's visitors have almost doubled due to the popularity of the "Wonder" exhibition. In November 2015, "Wonder" opened in celebration of the completion of a two-year renovation of the Renwick Gallery. The exhibition featured nine major contemporary artists invited to install site-specific works on the theme of wonder in the nine exhibition spaces of the gallery. The artists chosen were Jennifer Angus, Chakaia Booker, Gabriel Dawe, Tara Donovan, Patrick Dougherty, Janet Echelman, John Grade, Maya Lin, and Leo Villareal. The artists were given freedom to create their installations. Angus' piece, "In the Midnight Garden," featured over 5,000 bugs – beetles, moths, and cicadas – in various patterns in a pink room. Booker's "Anonymous Donor" was made up of old tires and stainless steel. Dawe's "Plexus A1" weaved a rainbow into the middle of one of the Renwick's rooms. Donovan made her installation out of thousands of index cards. Dougherty made his installation, "Shindig," out of willow branches. Echelman based her piece off of images from the National Oceanic and Atmospheric Administration that showed the impact of waves during the 2011 Japan tsunami. Grade reassembled a mold of a hemlock tree over a century year old. The piece is called "Middle Fork." Lin chose to map out the Chesapeake Bay using marbles. Villareal's LED chandelier hangs from the top of the Renwick ceiling. Since January 2016, over 176,000 people have visited the gallery. The "Wonder" exhibition is popular on social media, and the Renwick has been tagged over 20,000 times on Instagram by users. Wonder closed after eight months and drew 732,000 viewers. It was criticized for being inconsistent with the Renwick's commitment to American craft. The Renwick Craft Invitational is a biennial assessment of contemporary fine craft. The 2016 exhibition featured works by Steven Young Lee, Kristen Morgin, Jennifer Trask, and Norwood Viviano. Disrupting Craft: Renwick Invitational 2018 featured works by Tanya Aguiñiga, Sharif Bey, Dustin Farnsworth, and Stephanie Syjuco. Since 2011, the Renwick has hosted a quarterly "Handi-hour," a crafting-themed happy hour event, inspired by the DIY movement. In addition to craft activities for patrons, the 21+ event features craft beers selected by Greg Engert of the ChurchKey restaurant and pub in Washington, D.C. In 2019 the Renwick hosted an augmented reality exhibition by glass artist Ginny Ruffner and digital collaborator Grant
