I've had to deal with something similar to this a couple of times. Always fun.
Not sure how you did it, but the best tip I was given was to leave the lines connected to the kite, if possible. Make the untangling heaps easier.
I had this happen to me when I first learnt. I reckon its the sole reason I'm so absolutely anally retentive when it comes to running lines and packing them away. Usually run them twice setting up and at least once packing up. I also make sure that the end of the bar that the lines are secured at is the one that goes in the pouch down the side of the kite bag so that the ends dont get caught on stuff during transport.
I honestly had flashbacks of that situation when I saw that pic.
I don't see any tight knots in that lot so it should be a fairly easy one to sort out.
I'm with Galah on this one; two beers tops.
Even the most horrific messes i've had usually only take 3 or 4 beers at most to untangle. It's just a matter of determining if it's going to be faster to detach the lines from the bar or not.
don't you just hate it when..... you bought a five line kite instead of 4
Even better would be 2 lines
