i'd probably just build a light-weight lcd based bartop and carry it out when you want to play it...how often could you possibly find yourself wanting to play arcade games outdoors? i guess it depends greatly on the climate where you live, but here in Pennsylvania, this just wouldnt work. winter is out of the question because of the snow/ice. spring, summer and fall could be do-able, but during the day time, there would be too much light, making it difficult to see the screen. at night, it gets pretty damp, in the spring and fall it is pretty cool at night, and during the summer, it would be still hot and humid... why not just go inside where it is air conditioned and play games in comfort?
