Backing up (syncing) multiple computers help?

I have three computers:

1) Home PC with external hard drive

2) Work PC with external hard drive

3) Macbook laptop

I work with projects at home and at the office and on my laptop. I want to be able to synchronize files across all computers. When I work at home, I want that hard drive to have my project files. Then I want to be able to sync that with my laptop then take it to work, then sync that to my office computer hard drive so that the office hard drive has access to these files.

Then vice versa - go home after working on files, keep these files on the work computer, then syncing with laptop, then bringing it home, then syncing with my home pc.

What's the best way to do this?
