Blockchain 3D and VR Explorer (http://blockchain3d.info) is a free Bitcoin Blockchain browser available for Windows, Android (with Google Cardboard for Virtual Reality), Linux and MacOS.
This video demos it running on Windows.
The tool lets you enter a starting address or transaction, then navigate the Bitcoin network as far as you like (or as your hardware will allow, performance wise) to see inflows and outflows, all in glorious(-ish) 3D (or VR with Cardboard).
