Have you ever wanted to play around with Android on something other than your phone or tablet? Good news! You can download Android in ISO format from the developers web site: https://code.google.com/p/android-x86/downloads/list
After you’re done downloading the ISO, you can install Android as a virtual machine in a product like VirtualBox (which is free). At the time of this post, Android 4.3 is the most current version available with a download size of 199MB.
