We're fascinated with this beautiful mashup of reality and fantasy using 3D printing by artist Greg Petchkovsky, who created it as his entry to the Instructables "Make It Real" contest.
Petchkovsky first scans a broken brick corner and then using a combination of Agisoft Photoscan and 3DS Max he designed and 3D printed a part that fit precisely into the broken corner. The interesting bit is that the part mixes in something that shouldn't be there: LEGO bricks. Reality, mixed.
Watch the video and see how he made this amazing mashup. Be sure to watch all the way to the end of the video, as he shows more experimental work that could be even more interesting.
