Weekend Challenge: Particles Galore!

I’ve always loved tinkering with particles and physics, creating mesmerising shapes or motion. Rediscover the beauty of particle systems in this weekend’s challenge and create some wonderful abstract art!
Rules:
- Post your work in the comments below (yes, we have a nifty new ‘attach image’ option below the comments box for this!)
- Post only new work, not existing.
- Deadline: Monday April 24 at 23:59 (Amsterdam time)
- Yan and I will pick the winner.
- The winner will get a post next week, and will get to pick next weekend’s contest theme.
Have fun :)

Looking forward to this one xD!
And here’s some retro stuff
Here’s my attempt. Not the most fancy use of particle system maybe :)
Here’s my humble contribution. The background is a wallpaper I found on the internet, so not by me.
Hello, new here and my first try on a CG challenge of any kind, here is my humble contribution. At least I have a new wallpaper!! Hope you like it.
Hi anyone this is my entry, and it’s also my first post here on BlenderNation! A bit messy but i guess that’s what particles were created for :-)…
Here is my attempt
not perfect and still one minute late… ;-)
It was so nice by Blendernation to just completely ignore this contest. I know there are no prizes and since I saw a couple of really good entries I never thought about win, but anyway it was my first time in a contest and I put my ilusion in my render. I came back every single day since I posted it just becouse of the contest result, but there is no ilusion anymore. Thank you!! :)
