… is a gallery installation running from Jan 22nd, 2019 through March, 22nd 2019. It is made up of dynamic digital projections and music that incorporate a real-time feed of all the deletions happening on Wikipedia. There are an average of 155,520 edits a day on Wikipedia, some portion of which are deletions. What would it be like to stand near the drain where those deletions circle in their last moments before they are gone? Knowledge Lost is a eulogy to those bits of knowledge leaving us behind. Devoid of their original context, it is one last chance for those things to be known. And also a chance to know them as things not to know.


There will be an opening event on January 31st where the artist will be on site answering questions about the piece.
