At the end of 2009, the GPars project held a logo contest. This page was used to accept submissions and as a way of labelling the entries for the ballot. A multi-round, proportional representation system was used (details available on request). In the end two rounds of voting were needed to deliver a winner. On announcing the result, there was general agreement that the chosen logo was very acceptable ![]()
The winner is:

The logo was created by Jiří Kropáček.
The rest of this page is as it was for the competition.
Ideas
The GPars project delivers a collection of practical constructs for parallel (concurrent) programming in the Groovy programming language. Among the interesting and key concepts and words illustrating the project one should mention: parallelism, concurrency, ease of use, speed, performance, fun, joy, surprise, flow of data, independent actors / entities, synchronization.
What you gain
Your name as the logo author will be mentioned on the project web site. Since we strongly believe our project will grow into a well recognized brand, you'll gain recognition for your art work and your name will live with the project forever.
Deliveries
- Only logos on the logo competition page qualify for entry.
- The time limit for submission is 2009-Nov-30.
- There is no guarantee that one of the logos has to win, we could declare none suitable and reopen for nominations.
- The logo needs to be sensible at both 32x32 and 200x200 for use on the Web.
- The logo needs to have vector art original so that it can be scaled to any size -- it must look good at 2000x2000 for use in all print media.
- The logo needs to have transparent background so it can be sited anywhere.
Copyright transfer
By submitting your proposal to the GPars logo contest you agree to the following:
Logo authors retain copyright of their proposals whilst they are proposals. By submitting entries to the competition, logo authors agree that should they win the competition, they will transfer all rights in the winning logo to the GPars Project Leads (currently Václav Pech).
The reason for this is to do with branding: the logo is the most immediate part of the project brand and so it is important to be able to constrain use of the logo even though the project is a FOSS project. If you look at all the biggest and best FOSS projects, their brand is strongly controlled for marketing and legal reasons. The intention is for GPars to be up their with the biggest and best.
The future logo license
The licence for the logo will be a "use exactly as is" type licence, i.e. no change of aspect ration, no decoration, but use where you want. We are currently investigating whether the Creative Commons Attribution-Noncommercial-No Derivitative Works 3.0 (http://creativecommons.org/licenses/by-nc-nd/3.0/ ) would be an appropriate licence.
Submit your proposals
Submittions have been closed. Expect a baloot to be organized within the next couple of days!
The Process
After the closing date, a ballot will be organized on the GPars Users mailing list (user@gpars.codehaus.org), so if you want to vote, you need to join the list.

Use the Groovy star to show this is a Groovy thing and two vertical bars to represent parallelism. |

Use the // comment symbol to represent parallelism. |

Use an equals sign on the Groovy star chest to represent parallelism. |

Made during listining to grails podcast episode 97. I was unable to upload images into Confluence. Feel free to fix this. (I uploaded and inserted the images. Russel, 2009-10-15 07:00+01:00.)
- Picks up the popular curly brackets theme that a lot of groovy logos are using.
If you like it I can make a few variations (like more colours, more arrows, the "G" from "Groovy" (if I find the font), arrows starting at different timeline points and merging, ...)

The contest is pretty much over now that this beauty has been submitted. |

Monochromatic works well on shirts, etc... Hopefully could scale down well but might have to remove the "Get Parallel". I little worried about that. I also have a version that has color gradient dark to light from top to bottom. |
|
Just changed the slogan. Others are |
|
Gradient can be in any direction and any color. |
|
Vertical Gradient with a different sloagan. Text can change. Lines can change. etc. Logos imply processing in different directions (requests) all at once |

The movie "clap" is a reference to movie "actors", and the parallel diagnoal stripes remind of the notion of parallelism. |

Personally I really really think Dierk's grass logo looks cool.
Would be interested to see how you could combine the logo with the project name.

I like Philippe's proposal, and took it a step further (I extracted the 'g' out of groovy with illustrator)

Hamlet! That is the coolest logo I've ever seen. You really drew the zombie yourself??
For real, I think it would be really really cool to use that as a logo. Especially since Gpars sounds like "Jeepers" (what they always said in "Scooby Doo"). Could you do another variant of the logo with a zombie (or a row of zombies) standing next to the "GPARS!" name? I'm thinking of something more compact that would fit better on a site masthead.
But seriously, you just blew all other submissions out of the water. I'll be seriously disappointed if such a creative submission gets turned down.

Who said irony was dead :-)
Hamlet's idea could certainly be used as part of a marketing campaign as a advertising poster, but it doesn't really qualify as a logo.
There are many, many pages out there on good logo design, for example http://www.code-interactive.com/thinker/a112.html

I /really/ don't expect my design to win the logo contest, but I think playing up the Scooby-Doo "Jeepers" angle is fun. Russell is right about logos. Still, it would make a cool Cafe Press T-Shirt or something. Or do something with the "Creepshow" font.
