Contest is now on 99designs.com: https://99designs.com/logo-design/contests/monero-mro-cryptocurrency-logo-design-contest-382486Monero is new cryptocurrency based on the CryptoNote protocol. It's not a descendent of Bitcoin and uses new cryptography (ring signatures) to give a high degree of anonymity by obscuring identities with decentralized mixing. You can read all about it here:
https://bitcointalk.org/index.php?topic=583449.0Monero is looking for a logo and will pay a bounty to the winning designer. There's no set end date for submissions. The coin is primarily about privacy and the name is derived from the language Esperanto, but you don't have to incorporate either of those things. Something minimalistic is fine. The main component we're looking for is the coin design (i.e. like Bitcoin's white B in an orange circle), but a circular design is not mandated. A stylized rendering of the word Monero is entirely optional.
We will probably decide by discussion in the IRC channel since a forum vote is prone to ballot stuffing by new accounts. If selected, you may still be asked to tweak and play around with the fonts/color schemes before finalizing for usage.
