Mikey Sklar, who we previously mentioned because of his trampoline/fire mashup, now has a Flame Effects blog up for...well, exactly what it says it is.
This stuff is gorgeous and wicked. I must concur with MAKE Blog (where we found this), who posted the "Respirator" as their story's pic due to the item's coolness, no doubt. It's an EKG hooked up to the flames so they pulse in time with your heartbeat. Awesome.
