Sorting floating lines (end of next line has same x and y value as start from line next to it)

[chris.pm (Chris M)]

Hi
i have a bunch of lines. atm they are randomly sorted. i would like to get them sorted in one continous motion

like this:

i tried projecting the lines on the floor and seeing what end goes with what start. but I don’t know how to procede from here

any tips?
thanks
chris
