THE VIRTUAL TEMPLE PROJECT is the subject of an article in the Jerusalem Post:

Maverick visionary or eccentric academic?
By DANIEL BEN-TAL

Yitzhak Hayut-Man, a cyber-architect with outlandish ideas, is gaining followers

The imaginings of Dr. Yitzhak Hayut-Man (B Arch, MSc, PhD) undermine the very axioms of the mainstream academic and religious establishments that shun him.

The Hebrew media has ignored his maverick proposals for a floating hologram of the Third Temple and multiple-player interactive computer games "set in the Old City of Jerusalem and its celestial counterpart, the Heavenly Jerusalem that will enable multitudes to conduct a spiritual pilgrimage."

[...]

"Six potential investors wrote to say that they'd like to help, and I consulted with my existing team developing the game system. After we demanded that they sign a confidentiality agreement to protect our intellectual property, the interest petered out."

Hayut-Man heads the self-styled Academy of Jerusalem, a think-tank association of 20 "multidisciplinary visionaries. My main mission is to design the games, to show a truth about Jerusalem that nobody seems to notice: The [Third] Temple already exists. It's straight in front of our eyes, in the most conspicuous place. Depicted as a temple of wisdom and womb for the three religions, it can breed interfaith understanding."

He envisages a hovering holographic temple, projected by an array of high-powered, water-cooled lasers fired into a smoke-filled transparent polyurethane cube with a lightweight metal frame suspended beneath a blimp. The ephemeral, flickering image in the three-dimensional projection screen will fulfill an ancient Jewish prophecy that the Temple will descend from the heavens as a manifestation of light, he explains.

I have to say that his interpretation of the Dome of the Rock doesn't sound very likely to me:

"The Dome of the Rock, he explains, was conceptualized as an observatory into the fifth dimension. It was built as a 3-D model of a 4-D cube.

I don't think the mathematics to conceptualize this were in place in the seventh century.
