You can now add a Live PokemonGo Map to your Laptop / PC thanks to Mike Christopher at GitHub.
Why use PokemonGo Maps?
What Mike has created is a Pokémon-tracking map to help players figure out which Pokémon can be found in their areas and elsewhere. I guess you can pretend to be working in the office while you track Pokemons.
There are a few issues but it should work for most. Mike is working hard to resolve the issues.
