be sure to swing by the Isabella Stewart Gardner Museum to see Empyrean by Cliff Evans, a multi-multi-channel, five in all, high definition projection work. I haven’t seen the completed installation yet, and might not get up to Boston to see it there (but hear rumour of it coming to Chelsea, NYC, within the next six months), but I had a hand in assembling the computer running these high-def video channels. A barebones PC running a flavour of Linux OS, the machine uses open-source software across the board to power what is guaranteed to be a seductive array of moving images.
