we also have ~10kloc project at http://pcb.ng . Re-frame has been a real treat to use so far.

Same here couple kloc in one project, two in the prototype phase (hundrets of loc) and loving it

Are any of them OS so we can see the code?

5 months project, ~9kloc at Xerpa

~1500 lines of ClojureScript using re-frame at http://lumanu.com
