Many sci-fi fans wonder what classic Doctor Who might look like if the BBC bosses of the '70s and '80s could have budgeted more than £6 per episode for visual effects.

A new Who DVD set from BBC Video features a specially remastered episode that offers you just that experience.

Doctor Who: "The Black Guardian Trilogy" serves up a trio of 1983 Who episodes featuring Peter Davison as the Fifth Doctor in a life and death struggle against a supernatural evil force.

A team of restoration and digital effects artists took the final episode of that trilogy ("Enlightenment" -- a well-written, high-concept adventure featuring a simulated sailing race in deep space) and laid in 21st Century CG visuals.

Every once in a while, the British television show Doctor Who is revamped. This is usually done by replacing the lead actor and his supporting crew. However, it is also done by changing the logo of the series. As a result, certain logos are associated with certain eras. Yesterday, the BBC has revealed on their website the logo to be associated with the Matt Smith era of the show. They also have a video of the historical logos of the show.

I don't have a particular favorite logo, although I liked both the "diamond" logo of the 70's, most closely associated with Tom Baker's era, and the "neon" logo of the 80's, which spanned three Doctors (Tom Baker, Peter Davison and Colin Baker). The current one isn't bad either with the cylinder thing with pointy ends (what is that shape called?).

A video preview of thenew logo is available on certain sites such as Topless Robot. What do you think of it? Which logo has been your favorite?
