If there was one thing I appreciated about Interstellar, it was that at least they attempted to visualise the 5th dimension. Even if it ended up looking a lot like a giant building-sized piece of bismuth built out of shonky wooden library shelves, tracing paper, and a lot of black thread. At least they tried. I&#8217;d like to see more people try to imagine what it might look like, even if the representations fall flat on their faces.<\/p>\n<p><center><a href=\"https:\/\/www.flickr.com\/photos\/cobalt\/3256885659\" title=\"Bismuth Structural Rainbow by cobalt123, on Flickr\"><img loading=\"lazy\" src=\"https:\/\/farm4.staticflickr.com\/3526\/3256885659_5c0c9710d1_z.jpg\" width=\"640\" height=\"551\" alt=\"Bismuth Structural Rainbow\" \/><\/a><br \/><small>Bismuth from Flickr user cobalt123<\/small><\/center><br \/>The structural qualities of minerals is fascinating. On a personal level, I am attracted to rocks and geological features which are so orderly and angular that one imagines &#8211; that if the image were presented out of context &#8211; then one might just believe that it could be man-made, although in reality these shapes and forms are a product of nature. Like a artificial\/man-made mine, in which square chunks are methodically hewn out, or dug out to form huge man-sized hollow hopper crystal structures in which humans could nestle within&#8230; To think of planets as petri dishes for life with their respective larder list of minerals and baking temperatures!&#8230;<\/p>\n<p><a href=\"https:\/\/www.flickr.com\/photos\/arielst0rm7\/9820494743\" title=\"P9176643 by debbie ding, on Flickr\"><img loading=\"lazy\" src=\"https:\/\/farm8.staticflickr.com\/7287\/9820494743_34a74f6c14_c.jpg\" width=\"800\" height=\"600\" alt=\"P9176643\" \/><\/a><\/p>\n<p>Here for example, this is the Pool of Serpents (Poll na bpeist) &#8211; a naturally formed olympic sized pool cut-out in the rocks of the Aran Islands, which I went to see last year.

In my own digital paintings, I found that painting in some &#8220;shine&#8221; with pin-points of white light (like a 3D model) give an image a realism\/fakeness to them. I would make latex clothing if I had the resources to or if I were more inclined to doing something fashion related (as it were, I do intentionally avoid having to think too hard about clothing as I think time can be better spent on other things). But I enjoy looking at glossy and shiny materials, and I don&#8217;t understand why it has an image of being &#8220;kinky&#8221;.<\/p>\n<p><center><iframe loading=\"lazy\" width=\"640\" height=\"480\" src=\"\/\/www.youtube.com\/embed\/csK1bYMaBAA\" frameborder=\"0\" allowfullscreen><\/iframe><\/center><br \/>Perhaps I was born in the wrong time, and I think a skin-like rubber material like latex has an interesting shine to it and as a material for clothing it is more representative of the times. The question of how latex became kinky is something I shall have to look into further some other time, but to go on with the story&#8230;<\/p>\n<p>So this morning I continued experimenting with Meshmixer. I had drawn an imperfect klein surface and was hoping to figure out how to edit its shaders to make it less or more &#8220;shiny&#8221;.<\/p>\n<p><a href=\"https:\/\/www.flickr.com\/photos\/arielst0rm7\/15318190843\" title=\"Screen Shot 2014-12-03 at 1.04.57 pm by debbie ding, on Flickr\"><img loading=\"lazy\" src=\"https:\/\/farm8.staticflickr.com\/7489\/15318190843_348a3f2f66_c.jpg\" width=\"800\" height=\"487\" alt=\"Screen Shot 2014-12-03 at 1.04.57 pm\" \/><\/a><br \/><small>(I do apologise for this poor approximation of a klein surface &#8211; with a red &#8220;rubber&#8221; shader)<\/small><\/p>\n<p><a href=\"https:\/\/www.flickr.com\/photos\/arielst0rm7\/15315572714\" title=\"Screen Shot 2014-12-03 at 1.06.13 pm by debbie ding, on Flickr\"><img loading=\"lazy\" src=\"https:\/\/farm8.staticflickr.com\/7559\/15315572714_75f23a8433_c.jpg\" width=\"800\" height=\"463\" alt=\"Screen Shot 2014-12-03 at 1.06.13 pm\" \/><\/a><\/p>\n<p>Next, I dropped in a jpg of the Witch Head Nebula which I had cut down in size into a \u201cshader&#8221;.
