I think it is a 'superfly' artifact, due to 'only' 16 pixel samples. Firefly rendered 'reverse view' of scene quickly and, IMHO, better but, if you have the time for lots more pixel samples, 'superfly' seems to win-- E-V-E-N-T-U-A-L-L-Y...
And the lighting is far from optimal...
I'm still fumbling along the lowest holds on 'climbing wall'.
