Crayola allows tots to doodle on the iPad using its iMarker just as they would a crayon on a colouring book. Tweens are able to belt out their favourite Miley Cyrus and Selena Gomez tunes on a Disney microphone that turns the tablet into a karaoke machine. And technology accessories firm Griffin enables teens to fly its toy helicopter by using the iPhone as a remote control. Crayola iMarker transforms the iPad into a digital colouring book using Crayola\'s free ColorStudio HD application that parents can download. Children can draw and colour using the iMarker, which has a soft tip. Disney has three offerings. The ‘Disney Spotlight\' microphone, which is $69.99 or $99.99 for a wireless version, plugs into the iPad and allows kids to sing along to Disney songs from shows such as Hannah Montana — or to their own music — and record their own music video. Disney\'s $79.99 AppClix digital camera enables kids to upload their pictures to an iPad and a free app allows them add Mickey Mouse and Donald Duck into the photos. And Disney teamed up with Canadian toymaker Spin Master to create ‘Appmates\', a toy car based on the characters from the company\'s Car\'s 2 animated movie.
