$20USD via PayPal to the first person who is already following me, who comes up with a logo for the Sentinel 65X that I think is cool enough to use.
Condition: The copyright of the winner of the prize gets transferred to me, so I can put restrictions on its use.
What I want: A logo that is identifiable, public-acceptable (See AROS for an idea of what not to do) that screams "cool new retrocomputer", and that is not too close to anything out there now. Other than that, go wild.
