I'm brushing off some dust from my flash animating skills and quickly came up with this animation. Its a marker that will appear on screen (fade in) and then draw a circle and then disappear (fade out). I plan on using it to highlight items on the screen like buttons instead of using the boring old blinking boxes. Let the animation run as long as you need the circle to appear on screen. Right click to save.
*edit: updated the font to look more closely like the sharpie font. Thanks to Jeanette for the idea.
Let me know if and how you use it.
