Art-school PS3 downloadable title gets evolving

Following earlier news of the PlayStation Network from Sony, here's footage from its most striking downloadable title, Flow.

Originally a student-developed freeware Flash game (you can play it here), the creators moved in to Sony's Santa Monica studios to work on an upgraded PS3 version - boasting spacier sound, richer visuals and effects, and tilt-sensitive SixAxis controls.

Its chilled-out vibe doesn't translate so well to a two-minute movie, or indeed the floor of the Tokyo Game Show last month, but in play it's an addictive, absorbing and Sony-stylish title. Pricing for Sony-published downloadable games was announced at around $15 (£8) - it's unknown if Flow will retail for that price or a little cheaper.
