March of the Living offered a digital option of submitting virtual plaques with personal messages, which would be featured on the March of the Living website in the days leading to Holocaust Remembrance Day and beyond. The first plaque was submitted by Israeli President, Reuven Rivlin, followed by other well-known figures including Rabbi Jonathan Sacks and Mayim Bialik. On the eve of Holocaust Remembrance Day, a number of plaques were projected onto the guard tower and gates of Auschwitz-Birkenau. The current number of completed plaques is approaching 18,000.
