A 3D expo hall that's always open. Paste your website and a booth builds itself in about 30 seconds: your logo, your colours, your video playing on the wall. Visitors walk the floor on desktop or phone, click your booth, and go through to the pages you pick. Each booth gets its own numbers: who walked up, who opened it, who clicked through, how long they stayed. Free for 7 days, no card. 76 plots, priced like a real show in terms of floorspace, but way way cheaper :)
