I will have to agree with those who think that trying to come up with a symbol to represent Objectivism is an idle pursuit. However, if anyone wants to carry on with this idea, there are some aspects that should be firstly considered. In order to be functional, a symbol requires simplicity. It has to be easily readable and reproducible. The black and yellow image above has too many elements in it. Some of them are still incomprehensible to me, and nobody is going to stand in front of your symbol, staring at it and examining all of its little details. If you want it to be recognizable, the elements included have to be understandable at a quick glance. Otherwise, nobody is going to pay attention to it, and they will probably forget it a few minutes later. Take a look at some of the most well-known symbols, or famous logos from big brands. They all share simplicity. No one uses the Sistine Chapel ceiling as a symbol, when a red cross or a Nike Swoosh does the job. The last image is fine as it is. The other one looks like a ribbon awarded in a competition, or a text bubble from a comic book. Gradients are nice, but they are usually not advisable. Unless you want to invest all your money in full color impressions of a symbol with hundreds of inks, rather than just one or two, using gradients is probably not the best idea. The same applies to photographs. You must take into account its reproduction. There is no room for much detail or color when using certain physical formats, at least without suffering some type of distortion. The symbol should have a good size ratio, so that it can be still easily recognizable when it is reduced in size for smaller applications. I am curious about how far you are planning to take this, but the symbol has to be simple enough to fit in a pencil or in a golf ball. Also, you might like to add the word "Objectivism" to the illustration, so that people can start associating it with the symbol. The drawing by itself is not going to take you very far. You can drop the name when the symbol acquires enough recognition, but it is always necessary to include it at the beginning. Anyway, there is a lot more to take into consideration, but this should be enough for now.
