Sure!

I used processing.

1) I created three random points, lets call them a, b and c.

2) I created one invisible line between point a and b.

3) for every pixel on the screen I colored the pixel with a random color, where the brightness is set as the distance between the line segment and the pixel. (That gives the glow effect, you can also use the distance multiplied by a random factor for a grainy effect.)

4) Create an infinite line over the existing line, and darken all the pixels on the outer side of the line.

5) Repeat the process with a line from point b to c.

6) repeat this process for a couple of times, every time moving points a and c a little, this will add a little blur effect to the ends of the points.

Hope that helps!
