24-timmarsserie
Engelska "24 hour comic". Ursprungligen en idé av Scott McCloud som en kreativ utmaning för sig själv, och kollegan Steve Bissette. Idén går i huvudsak ut på att, utan egentliga förberedelser fullfölja en serie på 24 sidor (manus, skisser, tuschning etc.) från det att man börjat teckna.
If the cartoonist fails to finish the comic in 24 hours, there are two courses of action suggested: Stop the comic at the 24-hour mark, or continue working until all 24 pages are done. The former is known as "the Gaiman variation" after Neil Gaiman's unsuccessful attempt, and the latter is called "the Eastman variation" after Kevin Eastman's unsuccessful attempt. Scott McCloud calls both of these "noble failures", which he will still list on his site as long as he believes that the creator intended to finish the project within the specified amount of time.
