"Lots of twins have a special connection - being able to finish each other's sentences; sensing what the other is thinking; perhaps even knowing when the other is in trouble or in pain - but for 12-year-old twins, Matt and Emily Calder, the connection is beyond special. Together, the twins have extraordinary powers - they are able to bring art to life, or enter paintings at will."
