Here's a little example of the kind of cool abstract art you can make with this through a little tweaking in Blender. I'm not very good at it, but here's an example created using these techniques. (If you really want to know how I did this example - the material was just a grayish blue color, with an alpha map fading out to the right. The wireframe was just a duplicate set of the shapes, set to render as wire. The lensflare was Photoshop)



Delete the default cube in the centre of the scene if one is there already.

Switch to side view.

Press keyboard Spacebar > Add > Surface > Nurbs Circle



Press keyboard Tab to switch to object mode.



Switch to front view

Press keyboard Shift D to duplicate the circle and drag it to where you want to place it.



Press keyboard S to scale the circle to the size you want.



Press keyboard B and drag a box around the circles to select them. (It might help to move the lamp if it is in the way - press keyboard G to grab, and drag)



Press keyboard Ctrl J to join the circles.



Press keyboard Tab to switch to edit mode.

Press keyboard F to skin the object (makes faces).



Press keyboard Tab to switch back to object mode.

To convert your object to a mesh, press keyboard Alt C. You can press keyboard Z to see the model in shaded mode.



To smooth, click the vertex editing button , and click on Set Smooth and SubSurf. Set Subdiv to 1 or higher.

If you want your spike to have a sharp point, I suggest you do the following:

Press keyboard Tab to switch to vertex edit mode. Press the B key and highlight a few vertices at the pointy end of the shape. If you make a mistake, just press keyboard A to deselect all.
Press keyboard E to extrude. Drag the vertices to where you want them, and press keyboard S while holding down keyboard CTRL and scale the size down to 0.


You can also select all vertices by pressing keyboard A S X. That will let you select all vertices and scale the shape on the X-axis to stretch it out a little. Here is what I came up with:
