Random Moving Circles Blobular

Here’s something I did in the car the other day, it was mostly to try out some effects, but here it is. What do you think and how can I improve it?

I don’t know how cpu intensive it is, but it uses a lot of random functions. Is there any way to tell?

Edit: Gah, it’s gone all huge - how do I stop that? It looks much better the right size :wink:

Edit 2: there :smiley:

Edit 3: just looked in the task manager and it’s cpu usage is evil - sorry :stuck_out_tongue:
