google-gemini/starter-applets ? reverse-engineered prompt

Build me a set of small demo apps that show what Gemini can do with images, videos, and maps.

I want one app for spatial understanding, where I can upload an image and see Gemini identify objects, explain what is in the scene, and draw bounding boxes around things it finds. I want another app for video analysis, where I can load a video and ask questions about what is happening in it, with the app showing useful results in a clear way. I also want a map explorer, where I can search for a place and have Gemini help me explore it using Google Maps.

Keep the interfaces simple and easy to understand, with a clean demo feel. Make them work as standalone apps, and make it obvious where I put my Gemini API key so I can run them locally. Use whatever current Gemini and Google Maps docs you need to make the examples work well.
