When ideas come to mind, I find it imperative that I should try to work it out. The least I can do is to make a sketch or visualization of what that idea is all about, lest it goes to waste. The lowly saw horse is an example. There are many versions, from simple to complex. Some are easy to build the others require more advance skills. My version I would think is fairly easy.
The illustrations were done with “Wings 3D” a free software with features comparable to the costly proprietary software. My operating system is “Ubuntu 1004” (a Linux based OS), also a free software with features comparable to Windows which I gave up a long time ago due to its cost and proneness to viruses, malwares and spywares. Ubuntu is 99.99% virus, malware, and spyware free. Furthermore went an upgrade or improved version is available I get a notification form the makers and can obtain a download from them at no cost.
