Mainframe Studios and the Greater Des Moines Partnership bring back Tweet Week to downtown Des Moines for its second year with an artful journey that expands people’s appreciation and exploration of downtown.

The free interactive pop-up art event runs from July 9-16 with 80 colorful ceramic birds, created by four artists from Mainframe Studios, hidden throughout downtown. Starting Saturday, 10 birds will be distributed around the area for people to find in a scavenger hunt.

The Greater Des Moines Partnership shares clues on via @downtownDSMUSA on Facebook, Twitter and Instagram accounts or by searching #downtownDSM. Those lucky enough to find one of the birds can keep it and share images via social media using the hashtag #downtownDSM.
