Working from different machines.

Right now I have a server at work where I keep a bare repository as
a source and backup for projects.  So I clone a project from there
to my desktop, and work, making a few branches as I try out ideas
for new features.

Then I go home, and I want to work as though I was sitting at my
desktop.  If I clone the committed work, I don't get all my branches.
How can I work so that I now easily have all my branches, then after
I work at home, when I go back to my desktop, the branches now reflect
whatever state I last left them in?

In other words, I want to work from different machines, and always
sit down to the environment exactly as I last left it.

Thanks!
