Omeka Sandbox for Windows?

I am very new to Omeka. However, I have a Windows system, not the Linux system that Omeka requires, and as such, I was wondering: is there was a sandbox for Omeka available for Windows users?

I've been developing Wordpress themes lately and would really like to try my hand at developing an Omeka theme without having to install a completely new operating system or purchase services from a web host (just yet).

You can run Omeka locally on a windows machine for development purposes by installing Xampp for Windows, as some communities members do. We don't support that, so you would have to get it up and running yourself. Links to those options are in the Preparing to Install page in the Documentation:

Omeka cannot, however, run on a Windows web server. You must use Linux.
