Where's My Jetpack? 2. Breakneck's reliable roster of pop-addled artists — including Josh Usami, Eric Kaplan, and CHOD — memorialize what tomorrow looked like yesterday. (That's CHOD's "Space Cadet," left.) This retro-futurist show reimagines technologies from classical science fiction that failed to pan out, and reflects on how the unimagined digital age changed so much and so little. An opening reception will be held Saturday, August 25, from 6 to 10 p.m. The exhibit continues through October 6 at 17020 Madison Ave., Lakewood. Call 216-767-5610 or go to breakneckgallery.com for more information.
