GrafX2 is a bitmap paint program

GrafX2 is a bitmap paint program inspired by the Amiga programs ​Deluxe Paint and Brilliance. Specialized in 256-color drawing, it includes a very large number of tools and effects that make it particularly suitable for pixel art, game graphics, and generally any detailed graphics painted with a mouse. The program is mostly developed on Haiku, Linux and Windows, but is also portable on many other platforms.
Main supported platforms are:

• Windows: 2.6 Installer / 2.6 Portable / Nightly build (latest changes, may be unstable) 
• Haiku: pkgman install grafx2 
• Mac OS: 2.6 for amd64 or PowerPC 
• Linux: Nightly builds

You can download it from the official website.

Browser extension to download videos from the Web.

This extension to download videos from the Web can be used with Firefox and Chrome.
The main goal of this tool: downloads the video files from the webpage.
I was able to download files from web pages with the TS format file.
As you know, these files with the ts extension can be related to M3U8 files.
An M3U8 file is a playlist file used by various audio and video playback programs.
One short video tutorial can be found at the official youtube channel:

The RenderDoc tool graphics debugger.

RenderDoc is a free MIT licensed stand-alone graphics debugger that allows quick and easy single-frame capture and detailed introspection of any application using Vulkan, D3D11, OpenGL & OpenGL ES or D3D12 across Windows 7 - 10, Linux, Android, Stadia, or Nintendo Switch™. RenderDoc can be used as an image viewer.
If you drag in or use file to open then you can open images in a variety of formats like: .dds, .hdr, .exr, .bmp, .jpg, .png, .tga, .gif, .psd.
The tool come with python A.P.I. for testing.
The full features can be found here.
You can see the geometry data visualized in 3D and with each component separated out and formatted.
This tool can be found at the official webpage.

Heart shapes with Wolfram MathWorld.

I chose to present this resource today because it is March 8th.
There are a number of mathematical curves that produced heart shapes and you can find many tools on the web.
The author presents himself with a brief introduction:
Eric W. Weisstein began compiling scientific encyclopedias as a high school student nearly twenty years ago. Born in Bloomington, Indiana in 1969, Weisstein studied physics and astronomy at Cornell University and Caltech and received his Ph.D. from Caltech in 1996. In 1995, Weisstein took the vast collection of mathematical facts that he had been accumulating since his teenage years and began to deploy them on the early internet. These pioneering efforts at organizing and presenting online content helped define a paradigm that has subsequently been followed by other large-scale informational projects on the web.
The most important part of this resource is highlighted in a table of contents about mathematical issues:

• Algebra
• Applied Mathematics
• Calculus and Analysis
• Discrete Mathematics
• Foundations of Mathematics
• Geometry
• History and Terminology
• Number Theory
• Probability and Statistics
• Recreational Mathematics
• Topology

The examples and details can be found here.

Godot : water shader example.

This is an example created by user named Gonkee in this video tutorial.
The result of this shader tutorial I tested is this:
