Now that we are spilling our 3D hearts.
...I bought my first Realist in 1962 while in high school. I, too, got the bug from Viewmaster slides. I still have several disks from the 50s, and they are still in great condition. I have taken over 1000 Realist slides since the 60s, and most were taken in the 80s when my kids were born. So I have lots of 3D memories. About 8 years ago, I scanned all of these slides into digital files and used Stereomaker to align them. Recently, I've gone through them and converted many to 16:9 format to create a bluray for watching on my projector--the full frame effect definitely increases the feeling of being there. Over the years, I've had many different stereo cameras including the valued Veriscope F40, which was used, I'm told, to take the original Viewmaster slides. The small Viewmaster frames were created from those, and why they are so sharp. I also had a Viewmaster camera, but the quality was not that great. In the digital world I moved up to the Fuji W3 and the Panasonic 3D1 pocket camera, the JVC TD1, then the Sony TD10, then the Gopro 3+ system. Now dabbling in VR after my son showed me his Oculus Rift.
I saw the Bubble in 1967 and Warhol's Frankenstein in the 70s. The Bubble was great with lots of popouts, Frankenstein had good 3D, but awful content. I gave my son my 3D1 to take to Europe a couple of years ago, and he took hundreds of really great 3D pics. Problem will all of my 3D is trying to get others to watch it. The reactions are always mixed. Some like it, but most don't, and the glasses always drive everyone nuts, even the polarized ones I use for my living-room TV. VR might bring more people in the 3D realm, but it's a not a communal experience--unless you are playing a game with another person who is viewing the same gave, plus unlike casual TV watching, it requires total concentration, so it can be tiring to watch for more than 10-20 minutes at a time.
