Lanky Spider Model

[Tide-Arc Ephemera]

I would like a model similar to the normal spider model, preferably brownish black in colour... and I would like this sort of thing on it:

1) Has really long legs that shoot up about the height of trees (when bent)
2) Its legs are so long that it keeps its body off the ground
3) It moves in the fashion of a regular long legged-spider, sort of like a daddy-long-legs.

If you need any more details, then... please just ask.
