THEY are the designers of a consumerist future. Several of whom have redesigned the technology of today. Some of their creations: a tractor that facilitates operation while minimising hazards; a cane bicycle that replaces most metal parts with ethnic materials; a water cooler which can be folded up to blend with office furniture when not in use, a visual communication aid for spastics. These, along with 52 other projects, highlighted the story of latter-day Indian wizardy in the recently-concluded annual exhibition of the Industrial Design Centre (IDC), IIT Mumbai.
