As a member of the art team at Renaissance Church, I've had the joy of working on lots of amazing projects. One of the longest running series (and also the most temporary) has been these chalkboard murals, which typically lasted only a week. Corresponding with whatever was going on that Sunday, the type and illustrations carried a simple message that would soon be wiped away to make room for a new one. Several of of these murals are collaborations - thank you to the friends who lent a hand.
(The latest mural, showing the core beliefs and structure of Ren, stretches all the way across the chalkboard wall.)
