title: Particles.js — modify on frame-change
body: <p>Apologies for my complete lack of javascript intuition, but I was wondering if it is possible to change properties of a <a href="https://github.com/VincentGarreau/particles.js" rel="nofollow"><code>particles.js</code></a> object dynamically:</p>
  
  <p>I'm using <code>jQuery</code> to detect when a user moves a slider on the screen (successfully). However, I was wondering how to apply these slider-value changes to the <code>particles.js</code> canvas I have in the background.</p>
  
  <p>I.e. Move the slider across, and the particles get larger.</p>
  
  <p>However, I'm not sure how to update the <code>particles.js</code> — is anyone familiar with a callback or animation loop function that I can drop my property changes into?</p>
