"Handy Particles" is a script for #AfterEffects designed to create and manipulate particle effects. Its primary draw is the ability to use a variety of shapes for particles, including standard geometric forms and custom shapes. This feature stands out from the conventional, more limited shape options in After Effects' native particle generators.

The script presents a straightforward initial user interface featuring sliders for controlling basic parameters like the number of particles. This simplicity benefits quick setups, making the tool accessible to users of varying skill levels. However, this initial ease of use only partially captures the script's capabilities.

Beyond the primary interface, "Handy Particles" provides advanced customisation for #motiongraphics, within the effects panel. Here, each #motiondesigner can fine-tune properties such as particle size, direction, and colour. These advanced settings are crucial for detailed control and allow a more tailored approach to particle effects.

The ability to use custom shapes for particles is the script's most creative feature, offering significant potential for unique visual effects. This positions "Handy Particles" as a tool more suited for visual creativity and quick tasks rather than for complex particle simulations.

"Handy Particles" integrates perfectly within the After Effects ecosystem, complementing existing workflows. This ease of integration is a positive aspect, especially for users looking for a supplementary tool to enhance their particle effects repertoire without disrupting their established processes.

In essence, "Handy Particles" is a useful addition to the After Effects toolkit, particularly for designers seeking a balance between ease of use and creative flexibility. Its unique shape capabilities and user-friendly interface make it a valuable resource for adding distinctive particle effects to projects.
