An electronic sequencer and synthesizer has been built based on designs produced over 40 years ago by electronic music pioneer Daphne Oram.

Daphne Oram who died in 2003, co-founded the BBC Radiophonic workshop and developed a system of creating sounds and compositions using drawings.

The 'Mini Oramics' machine is thought to have remained unfinished in Daphne Oram's own lifetime, but experts argue that its approach to composition and performance would have been influential.

Tom Richards, the researcher who finally constructed the Mini Oramics, told The World At One it helped answer the question "what if this had come to pass in 1973?"
