The Dreamcast Kiosk is a display kiosk used by stores so that users could test the Sega Dreamcast console (and its games) before purchasing a copy for themselves, something that had been tried with many systems in the past. Typically a kiosk would contain a CRT television, Dreamcast console and two controllers, reinforced in such a way that VMUs could be displayed but not be stolen.
As the console was marketed differently between regions, Dreamcast kiosks look wildly different depending on which country they're from. North American kiosks are black/orange, while European models are white/blue.
