That device reminds me so much of one of Doraemon's device-of-the-episode, right down to the function and design. Well, I guess that's one way your childhood catching up with you.
Reminded me of the artist Asagiri manga, where the guy got the machine and used it on his next dor neighbour hot wife....But this is awesome too.... Great work, thank you Mr Artist and @Chilla4000 for the upload...
