Arthur T Knackerbracket has found the following story:
Under the right circumstances, Gaussian blurring can make an image seem more clearly defined. [DZL] demonstrates exactly this with a lightweight and compact Gaussian interpolation routine to make the low-resolution thermal sensor data display much better on a small OLED.
[...] used an MLX90640 sensor to create a DIY thermal imager with a small OLED display, but since the sensor is relatively low-resolution at 32×24, displaying the data directly looks awfully blocky. Gaussian interpolation to improve the display looks really good, but it turns out that the full Gaussian interpolation isn’t a trivial calculation write on your own. Since [DZL] wanted to implement it on a microcontroller, the lightweight implementation was born. The project page walks through the details of Gaussian interpolation and how some effective shortcuts were made, so be sure to give it a look.

Well, not *literally* nobody. Some people enjoy starting from (nearly) nothing sometimes. I've got a friend that decided to make himself a goatskin drum. Step 1: knap a stone scraping tool in order to scrape the raw uncured hide...

I have a lot of respect for that, but he didn't start back far enough. I presume he went out and found the flint, which is great, but I suspect he drove somewhere while wearing clothes and boots and used tools to get the stone. He needs to start naked in his back yard and work up from there. Otherwise, he started in somewhere in the middle.
