General
The throbber artwork is an animated icon which provides visual feedback of activity. To create the effect each frame of the strip is played left to right in a continuous manner.
~+Specifications+~
The dimension of the image strip is 288 x 24 pixels consisting of twelve individual 24 x 24 frames. The word "frame" in this document simply refers to an area on the drawing surface. If the desire is to create a spinning illusion with the image completing one revolution (360 degrees) in the space allowed, each frame must be rotated 30 degrees clockwise from the previous frame.

It is important to note this is not the only illusion that can be created. Images modeled on audio db meters or morphing colors are also appropriate.
~+Current Design+~
Taking a look at the current design each frame is filled with an image drawn with a series of circles to form the illusion of movement. A variant of this design is also used by the cursor.

~+Designing a Replacement+~
For purposes of illustration I created an image in Inkscape (Gimp would also work) adhering to the specification of twelve 24 x 24 frames. In the first frame I drew a circle with a light blue gradient (#00bbff) border and a transparent center.

Copying the image of frame one to the center of frame two I rotated it 30 degrees in a clockwise manner. Copying the image of frame two to the center of frame three I rotated it 30 degrees in a clockwise direction for a total of 60 degrees from the first. Continuing this process I created ten additional frames for a total of twelve.
The result of this effort looks like the following.
