 # insecam desk widget (LilyGO T-Embed)
 
 A little window onto the world's public webcams. The T-Embed's 320×170 IPS
-screen shows a random camera from [insecam.org](http://www.insecam.org) — as
-live MJPEG video where the camera streams it — and moves on to the next one
-every 20 seconds. The knob steps through cameras, the LED ring drains as the
+screen shows a random camera from [insecam.org](http://www.insecam.org) or
+[opentopia.com](https://www.opentopia.com) — as live MJPEG video where the
+camera streams it — and moves on to the next one every 20 seconds. The knob steps through cameras, the LED ring drains as the
 countdown runs. Everything happens on the ESP32-S3; no bridge or PC needed.
 
 ![The widget on a desk, paused on a favourite Tokyo camera](docs/widget.jpg)
 
-insecam lists cameras that are reachable on the public internet without any
-password. The widget only ever does what a browser on that site does: fetch a
-listing page, then fetch the camera's own snapshot/stream URL.
+Both sites list cameras that are reachable on the public internet without any
+password (opentopia leans towards harbours, ski slopes and campuses; insecam
+towards forgotten IP cams). The widget only ever does what a browser on those
