Karl Litten seems to be a busy guy. A limited search comes up with over 30 courses and in a few different countries.
I've played a couple, a really enjoyable one is Twisted Oaks in Beverly Hills Fl., s. west of Ocala, near Black Diamond. Some good holes, with a wide open roller coaster of a par 5 18th. The green is snuggled into a hillside on a diagonal to the fwy., and well protected. Actually, there is quite a bit of elevation change around the whole course. Feels more like the Carolinas than Fl.
