Those who once peered into their trusty View-Masters for 3D slideshows will soon get the chance to do the same with their iPhones.

View-Master, an oldie but a goodie.

Hasbro is set to pull the curtains on a new gadget today dubbed My3D and designed to bring 3D viewing to the iPhone and iPod Touch, according to the Associated Press. Resembling a classic View-Master from Fisher-Price, the My3D from rival toymaker Hasbro will hook onto Apple devices, promising 3D games, entertainment, and virtual travelogues.

Hasbro is targeting the $30 My3D for adults as well as kids and is working directly with Apple to develop the gadget, the AP reported.

To create the content, Hasbro is teaming up with a variety of companies, such as Dreamworks Animation. Hasbro will offer trailers and other movie snippets from a 3D network to be launched next year by Discovery, Sony, and Imax, the AP said.

My3D is scheduled to hit the market next spring in Apple retail stores and other outlets that sell the iPhone and iPod Touch. Consumers will be able to browse Apple's App store to download 3D apps, both free and paid.
