We seem to have some sort of a fetish with unique clocks around these parts and this single-digit clock definitely tweaks my clock-fetish nipples. This clock can still actually display the time in a sequence; one digit at a time. It's not actually very jumbo, as the name describes, by measuring in at approximately 3-inches tall by 2-inches wide. $22.

I have an alphabet populated by characters possible on digital clocks like this — it would be fun to hack a handful of these to do my bidding.
