According to Lauren Aaronson of Popular Science, Charlie's expertise seems a little bit incredible. Robert Bianco of USA Today, however, called Krumholtz, as Charlie, "appealing". Toni Fitzgerald of Media Life Magazine stated that Krumholtz, as Charlie, "stands out". Since the early days of the series, the character of Charlie Eppes has become more widely accepted. Krumholtz appeared at the 2005 National Council of Teachers of Mathematics (NCTM) convention in Anaheim. Since then, Krumholtz receives cheers when he attends math conventions. In a public service announcement, Krumholtz congratulated the Federal Bureau of Investigation on their 100th anniversary. Charlie was one of the first geeks on primetime television who paved the way for other shows starring geeks such as Bones, Chuck and The Big Bang Theory. Charlie was a runner-up in the category of "Sexiest Brainiac" in TV Guide's poll in 2007. CharlieVisionCharlieVision'' (as labeled by the show's creators) is the mode in which Charlie's insights are displayed on-screen. It consists of fast-paced visions or cutscenes often characterized by false-color images that integrate his analogies and mathematical models, usually followed by him rushing off to tell Don about his new insights. 'CharlieVision' is not to be confused with "audience visions," in which Charlie's voice uses an analogy to simplify a mathematical concept while corresponding images are flashed on screen. Ridley Scott and Tony Scott, executive producers for Numb3rs, designed the specifics of the Charlie-visions, such as the ash yellow color that appears on-screen when Charlie suddenly becomes inspired.
