In 2013, Boo won the President’s Young Talents Credit Suisse Artist Commissioning Award for a video art piece, Mirror. Later that year, he participated at the Singapore Biennale with Happy and Free, a video installation that depicted a Singapore that remained a part of Malaysia in 2013 and was celebrating the 50th anniversary of the territories' merger. Boo's short film, "Parting" was released as part of the omnibus titled 7 Letters (2015) to commemorate Singapore's 50th year of independence.
