Five things to do this weekend: Sept. 30-Oct. 2
Chuck Hoberman’s 10° art installation from noon to 9 p.m. Friday and from 11 a.m. to 10 p.m. Saturday at Le Laboratoire Cambridge, 650 E. Kendall St., Kendall Square. Free.
These four kinetic sculptures by internationally renowned designer and inventor Chuck Hoberman are original, origami-like folding mechanisms called “prismatic structures” that can be effortlessly transformed by viewers through hands-on play – even though they’re between 300 and 600 pounds each. Researchers at Harvard’s Wyss Institute for Biologically Inspired Engineering (including Katia Bertoldi, James Weaver and Johannes Overvelde) contributed to these works, inspired by questions such as “Could you design a house that could fit in a backpack?” and “Could you design material that can withstand the weight of an elephant without breaking and pop right back up for the next task?” Information is here.
Best of Boston Sketch Comedy: Night 1 from 10 to 11:15 p.m. Friday at ImprovBoston, 40 Prospect St., Central Square. Tickets are $18.
See how good local sketch comedy can be with work from the troupes Baby Cut, Klondike Radio Theatre – a live-action radio show with sound effects and Vitamin Snake (above), called “one of the most bizarro, offbeat sketch groups ever featured at ImprovBoston.” Kevin Quigley and Laura Clark co-host. The next two Fridays will deliver more sketch groups. Information is here.
Then We Move: Modern Dance for Street Pianos from 2 to 3 p.m. Saturday at Jill Brown-Rhone Park, near Central Square (free) and Movement Slam from 6 to 8 p.m. Saturday at Green Street Studios, 185 Green St., Central Square ($8 cash or card).
Dancer and visual artist Emily Evans (above) and fellow movement-based artists Caroline Carbo, MaryRose Blandino and Soshi Moyer perform free dance inspired by the “Play Me, I’m Yours” street pianos placed around Cambridge and Boston – specifically the one Evans painted for this plaza – and the visceral joy of live performance. (Information is here.) If that hour of performance sparks an urge, kill three hours in Central Square and check in to the Movement Slam for an experience that incorporates storytelling, improv, dancing, acting, playing around and moving, led by artistic director Tyler Catanella. “Get your body sweating, meet new people and join our community,” organizers are telling people of any experience level. “Just bring your personality and sense of play.” Information is here.
“Wall to Wall: Art Builds Communities” opening events from 1 to 6 p.m. Sunday at The Nave Gallery, 155 Powderhouse Blvd., near Teele Square, Somerville. Free.
Dubbed “W2W,” this is a gallery exhibition of street art and street-inspired studio art showing how visual creativity builds community. Held in conjunction with the Clarendon Hill Presbyterian Church social justice program “Learn to Talk” and Somerville’s legendary Honk! Festival of Street Bands, it includes an exhibition, artist talks and other events and activities that engage participants in a dialogue about building a more equitable community. The exhibition is up through Oct. 30, but it all starts Sunday with refreshments, an artist’s panel and presentations keynoted with a talk by world-renowned muralist and street art historian Caleb Neelon. (Boston community artist Cedric Douglas will participate as part of his UpTruck/UpWall project.) Information is here.
