Space Harrier. Super Hang-On. Out Run. Thunderblade. All are immortal hydraulic monsters released to arcades by Sega in the mid-1980s. And all are now tiny wee things that sit on your desk.
There's a secret fifth game, which is probably Afterburner, and the set will be $49 when it ships in April: you can already pre-order it at NCSX.
These little fellas are really small -- about 10cm long -- but I wonder how hard it would be to make something similar with a real LCD display, running the (emulated) game in question. PocketCultMame springs to mind...

A couple of weeks ago during the 48th Shizuoka Hobby Show I spotted the 5th "secret" model that as ROB predicted is AFTER BURNER.
From the photos I took it's possibile to see that these new models are super detailed and way better than the 2 years old miniature racde machines models released by SEGA for the crane games.
All the best from Tokyo!
