The digs I have been on use a surveyer's ranging pole (red/white bands), which seems to be fairly standard. But it depends on what "small" is: a ranging pole would be no good to show the size of a coin, but a ruler would not be useful to show the size of a small building. Size matters.

 [LanX]: all combinations with same amount of left and right? [Eily]: if you want to store in a structure with the coordinates as key, arrays might do, since the keys are going to be 0..n [LanX]: (Pascale path) [Discipulus]: yes Eily++ (very keen) I want to integrate my project with a 17th experiments. I want to colorize in sequence all paths [oiskuu]: Yeah, modifry the recursive func combinations() to return not the number, but the paths themselves. [Eily]: Discipulus I'd do that by starting from the bottom node I think. That way it can inherit the paths from the two nodes above (and so on, recursively) [LanX]: oh I meant fixed amount [LanX]: every path must have l left and r right edges and l and r are fixed and l+r is the height [LanX]: simple recursive function which goes left and right till l or r are exhausted
