Daleks, those fearless aliens made out of old cardboard boxes and egg packets, have made a comeback on the Web.

The BBC last week released a new Dr Who episode, which was originally planned for broadcast on Radio 4, online at http://www.bbc.co.uk/cult/doctorwho/ death/.

The episode sees Sylvester McCoy taking up the role of the doctor in combat with his age-old foe in an audio adventure with accompanying slide show. Stephen Fry and John Sessions also appear in the show, which is called Death Comes to Time.
