Try not to get hung up on using stones as the main design element. It's more important that the logo represents the feeling of the company and it's products instead of the logo blatantly representing the name of the company. We are not a paving company.
We can't release any of our artwork at the moment but I urge you to look at the artwork at the Dinotopia website for inspiration. The colours, materials, style and old world fantasy feeling is exactly what we want people to experience when they see our logo.
• The logo must be simple enough to be clearly read in the corner of an app icon. I have included examples of app icons that do this successfully.
• All of our books currently in production are timeless classics and have an element of serious drama and old world atmosphere to them - such as The Snow Queen, The Reluctant Dragon, The Legend of Sleepy Hollow, The Velveteen Rabbit etc. I have included images of Ireland and elements of Irish pottery, buildings and materials that exemplify this feeling. The name Cobblestone is meant to invoke this feeling, it is essential that the logo reflects this old world feeling, rather than simply following a stone motif.
• It Should be something that can be animated for opening credits - eg Legendary pictures, paramount, WB
• Our books have 3 versions in 1 different age groups - 3-5 year olds, 5-9 year olds and young adult. Perhaps the logo can reflect this 3-tired nature of our products - this is not an essential element, however.
• I have included examples of iconic logos that I like. I chose them because they are readable at any size and for the strong clear feeling they invoke. I have also included some modern logos that can be used as examples of logos that can easily be animated if needed, such as Swing Studios, Valiant Interactive, Urban Chic, Flow Music Productions and Flat Land.
• I like the simple power of modern vector logos such as the icons for Half Life 2, Nuke etc. Is it possible to make a simple iconic vector image that has an old world feeling?
• The illustrations in our books will be realistic - similar in style to Dinotopia by James Gurney http://www.dinotopia.com/
The icon samples are now downloadable so you can examine them closer. However, note how some of them are perfectly readable even when they are tiny...
