You mean, an Amanita Muscaria trip? My God no, that can kill somebody, Ufffff!!! Ha, Ha.
Well I know that there are other ways of doing anaglyphs, I know that there are free programs that can create them faster but this was just a way to do it manually without having to install any software if you already have Photoshop or the Gimp and it's intended for low volume and in Photoshop you could probably create an action and load the left and right images as layers and apply the action automatically and then you save that action as for the Gimp the only way to do it I believe it's through some sort of scripting or external robotizing software, for high volume of pictures or a lot of frames I recommend some software programs available for the for the purpose but I feel that you probably know about them already. I'm also aware of some special media players that can play two movies at the same time (one for left eye and one for right eye) and support different methods of stereoscopic playback including blue-red glasses, LCD shutter glasses and dual projectors (for polarized glasses) and other methods but I've only used them with red-blue glasses so far. I heard about the programs that take a regular picture and create a stereo one but I haven't experimented with it yet because I have been busy with many other things but I do like the subject of stereoscopic viewing a lot. I've been interested in it and virtual reality all my life and I went to Disney World (to Epcot) to see several of the polarized glasses movies in the Kodak pavillion and I liked it a lot cause it's way better technology than red-blue glasses. I also experimented a little bit with stereoscopic imaging in Blender 3D and learned how to create a rig with two cameras to simulate the different eyes point of view and make the two cameras track an object (can be an empty object) and create stereoscopic rendering, it's really not that difficult to do but of course you have to know 3D modeling and animation first but I think that there are a lot of interesting things that can be done with that, I just haven't have the time yet to do more. There was a new script released recently for Blender to set stereoscopic cameras, I haven't tried it yet but I took a look at it and it seemed interesting but like I said I had already been able to do it successfully for still pictures and animation without any script but I only tried it with very crude animations because of the large rendering time it can take to render animations of higher quality and complexity but it's a fascinating subject anyway, with the proper equipment the effect can be very convincing.
