Today, apparently, is the official Guinness World Record Day, and people are celebrating accordingly. As per to the Daily Mail, various record-setting attempts will take place today, including those for the farthest backwards basketball shot and the most people eating breakfast in bed. Kicking off the festivities last night near London’s Tower Bridge was a gathering of the largest-ever crowd of people in penguin costumes. As for records in the visual arts? artnet News has you covered with a round-up of the best art-related Guinness World Records.

Largest Mural of Recycled Materials
Moaffak Makhou
Earlier this year, Guinness officially recognized this gorgeous Damascus mural, a 7,750 foot-long marvel created by Makhou and his team from bicycle parts, mirrors, cooking utensils, soda cans, and ceramic shards (see “In Syria, Mural Sets New World Record“).

Largest Collection of Harry Potter Memorabilia
Menahem Asher Silva Vargas
Based in Mexico City, Silva Vargas shattered the old record of 807 with his 3,097 pieces of merchandise related to the Harry Potter book and film series (see “Guinness Honors World’s Largest Harry Potter Collection“). Though a world record is rewarding, the cost of collecting on such a scale adds up quickly: “My salary, my bonuses…it all ended up here,” he told the AP.
