Streaklet is a long exposure, light painting effect that is controlled by the Streaklet group. The base particle type is the Streaklet particle, which is a large particle dot surrounded by smaller particle dots. Note that the options in the Streaklet group are only available when Streaklet is chosen from the Particle Type pop-up.

At left, the Streaklet group. At right, the Streaklet option in Particle Type.
Random Seed: Randomizes where the small particle dots are positioned. Changing the Random Seed value can quickly give a different look for the Streaklet particles.
Left to right, different Random Seed values chosen.
No. Streaks: Sets the number of smaller particle dots around the main dot. High values make more streaks, which give a more detailed look. Lower values make fewer streaks and give a more simplistic look.
Left to right, No Streaks at 5 and 20.
Streak Size: Controls the size of the main particle dot. Low values create thinner, more separated streaks. High values create thicker, more overlapping streaks. A value of 0 turns off the streak.

Streaklet presets: Using the Box – Strings base form, some creativity and a little scripting, you can use Streaklets to create interesting light-filled compositions like the ones below. Several presets using the Box - Strings base form and Streaklets can be found in the Lines Presets in the Designer.
Some options using Box - Strings as a base form and Streaklet as the Particle Type.
