coveting cold frames

it's cold and rainy out there today. not much happening in here. but i did come across this blog post with a super awesomely cool cold frame/mini greenhouse. i've seen a many of cold frame made of old windows, but it never crossed my mind to do a mini greenhouse type version off the ground. i want one, i want one. oh how i want one for my back patio. let the back alley savaging begin!!!! also check out some other cold frame designs here.
