The Table Tennis Triples and Modular Table Tennis System (MTTS) was a finalist in the Australian Next Big Thing Awards.
I love how the invention's "unique benefits" are listed on the award site:
"- More people play on one table: social benefits, reduced waiting times
- Greater shot range, fairer 'Triples' scoring system
- Conventional tables can be reversibly 'Triples' retrofitted
- Numerous games/table shapes possible with the MTTS sectors"
