I have to say your last creation already looks great Maemish!
The shield shows we defend something and on the shield, which has its border already following Maemos color scheme, there are the building blocks of our beloved system.

I am curious what you will create. Maybe the pirate party sticker on my N900 has to give up its place in favor of your next image.

Exactly macros.

and hardly maemish...

If you are content with the depth of meaning you wish to impart to others with your crest maemish...then don't fret. Macros likes it. I like the latest. It does on the surface show the most obvious primary influences which are important to us.

If you wish for more meaning poured in to the crest though...
click and paste won't cut it.
At the least, you will have to take those 4 quartered logos and manipulate them in a graphic program to pour more "intent" into your crest.
It doesn't take much though ...this is not a herculean effort.
if necessary to convey more desired information then possibly
changing the placements of the icons,
changing their colours,
changing their backgrounds,
changing their postures
changing the directions they face or look or gesture to.
innocuous or exaggerated flourishes could be used where applicable.
just remember you don't need to put tons of visual graphic into the crest.
Heraldry isn't about clutter, it is about depth through purposeful simplicity

Then when done make sure to have a write up ...
say in bullet form
of every nuance according to the applicable laws of Heraldry.
Then you will have done (even if you feel it is rudimentary) a masterpiece everyone will marvel at as they follow your bullet form "legend" and see the interactions you have made come to life.

Everything was just grabbed or copy pasted from net as a draft idea. I will do the next so that it is really self made the end result. Gonna be different but got an idea.

I'm really looking forward to your attempt to create a crest for us; You seem to have already some inspiration and I have no doubt gentle guidence from @endsormeans will polish it up to deserved glory!

I have found that @endsormeans possesses great dephts of wizdom on crafts and arts but there is one nit I'm picking here;

Regarding Heraldy this might or might not be true, but regarding any written language ever used and invented by humans whether ancient pictograms or any phonetic languages; All of those are capable of teliing lies, inaccuracies and fables.
It is in the deep nature of our intellect to be able to spin either complete lies or truths into conciese and self-integral pieces of literature.

lies are different from inaccuracies and fables.
To understand this one must inspect what exactly a lie is.
It is easy to use the word, it is easy to think it is easily understood
concept, and it is easy to see it in retrospect once the lie is used and afterward uncovered.

A lie is an incomplete.
This is seen in everyone from children to elder states people.
The use of a lie to hide information, and subsequent inspection of details surrounding the situation, almost uniformly dictate the individual must needs create more lies in an effort to make the initial lie have a life, have substance, make sense in the light of said inspection.
A murderer caught says it wasn't him. A lie.
When asked where he was during the murder, the murderer says "anywhere but the scene", or concocts an alibi to sustain the lie, that has the ring of truth." . More inspection of the situation may determine facts which are opposite the murderers statement.
The best lies have the ring of truth to them, they are harder to see, to detect, because they utilize the natural truth of the situation or circumstances.
The most easily seen type of lies are omissions.
Not telling the whole of a story or situation.
They are noted by the uneasiness one feels that a hidden thing has not been integrated into the story ...a blank spot ..

Fables legends stories and myths ...they may not or may be factual or have been exaggerated or mashed together with other stories over time, but they are more truthful and have the staying power of their method of construction to prove them to be other than lies.
Whereas propaganda and manipulation to deceive doesn't .

The topic of lies and exactly what they are would fill many papers, and would make a number of great thesis ...thesises? ....thesi?
(moose ...meese)

As far as me and "gentle guidance" goes...
I have said more than enough on the topic in generalities ...
I go into specifics ....and it will just colour maemish and influence the direction he wishes to take.

There are plenty of online reference materials on Heraldry ...
the lists of "rules" so to speak...
easily found I would imagine...
(personally I have a few large hardcovers in my library on the standards of Heraldry)
the "rules" of construction haven't changed in centuries ..
so a specific inference is just that...
He can plot out everything quite well without my help...
start with the general background.
Then focus on the central icons involved...their positions and postures
then their colours and backgrounds ...
work from the ground up like most construction ...
a good big huge piece of paper to scribble on would help...
always helps ...
computers are great ...
but for ideas ...first...
nothing beats paper and pencil for jotting ideas .

Already made a design by myself. It may or may not please others. Made a 30cm high and about 20cm wide wooden crest. Next step is to paint it. Nothing done with computer. All hand drawn and painted. Personally I think I am happy with the end result. Hope someon else too. But to please someone with a heraldic knowledge and wisdom - I think it is too hard and time taking task for me. I am a fast moving spirit, both for my benefit and loss. We'll see.

Edit: Base paint job done. I may get it finished in couple of days. So far so good.

Finished the crest and put it in a new thread I opened.

And that thread is here, for the benefit of future generations who may not see it in Active Topics:
