Hmm...I wonder why that is. Anyway, you can change that by changing the line Code: x = (lx*8+(average(l3x)/800.0+0.5)*height)/9 to Code: x = (lx*8+(average(l3x)/(-800.0)+0.5)*height)/9 in server.py. I should add a command line flag for that.
x = (lx*8+(average(l3x)/800.0+0.5)*height)/9
x = (lx*8+(average(l3x)/(-800.0)+0.5)*height)/9
