Others have answered your question about landing on land. So I thought I'd just link the pictures you asked for.
The initial (publicly shown) iteration was Grasshopper, it looked like this [0].
After that there was F9R-Dev, which looked like this [1] (it's pretty much just a F9 first stage). At some point they added grid fins, which look like this on the vehicle [2] and this up close [3] (note the anti-pidgeon spikes are being added purely for display, they are not attached during flight). Other than that there haven't really been any visible iterations, the legs look like this [4] and have since the F9R-Dev.
