We are looking for a logo that can be used on our website, business cards, and other collateral. Logo can be variable, fluent, not static, to allowing recognizable branding and dont be trivial "golden ratio symbols"

We want to convey a message of "simple" and "fast" to our customers. It should be "inviting" and "friendly".
