Pulsu is a project that empirically analyzes which are the mechanisms that plants use to communicate and also how their own biological processes are a manifestation of communication, seemingly intangible to our senses.
lays each specimen on color transparency film and, for a more detailed effect, covers it with a diffusion screen. This assemblage is placed on his "easel"—a piece of sheet metal sandwiched between Plexiglas, floating in liquid silicone. Buelteman hits everything with an electric pulse and the electrons do a dance as they leap from the sheet metal, through the silicone and the plant (and hopefully not through him), while heading back out the jumper cables. In that moment, the gas surrounding the subject is ionized, leaving behind ethereal coronas.
