First of all, when you want someone to look at your
scene, you need to supply a working scene, with
a camera, at least one light-source and then
the object.

Then, your "scale 10" at the end can be changed easily
to something like scale .1 or such.

Finally, your blob is positioned awkwardly (why would
something be placed in the region of <1300,100,-1>?).

Most of the time, it is best to model an object on the
origin (<0,0,0>) and then position it later using translate.

Hope this gets you going... :-)
