I'm digging Mike Serafin's tons-o'-sketches for this hurricane lantern, done for a client in Moradabad, India. "[It was] a quick 2 phase project with some material and cost restrictions," reads Serafin's Coroflot page. "The result is a minimal, simple to use, large size lantern/hurricane which is easy to fabricate."
I also enjoyed leafing through Serafin's 'Flot page, as he not only cranks out the de rigeuer computer-based stuff...
...and even something I haven't seen in ages, one on craft paper.
I assume these sketches for a portable camping stove and bike pedals were done the new-fashioned way: drawn on paper with pen, then scanned into Photoshop.
I like this design for a one-piece hanging bottle of some sort—the cutaway of the tree branch it's hanging from suggests a camping application—and I desperately want to believe those white dots are actual gouache. If they even make that stuff anymore.
