Congratulation Plusminus and your team for the site, it's awesome.
Marvin: 100% mobile geo-editing and browsing solution.
Marvin allows you to publish and browse geo-localized objects around you.
Marvin is not "yet another map application"...
Objects can be static or move by themselves and follow you.
You publish and browse where you are, based on your current location or where you virtually are on the map.
Multiple presentations are available
Map, 3DMap, Tron (visually simple and lightweight visualization)
MStreet: Augmented reality using StreetView content (yes, really…)
