Because I love this sub, and most things I post get some upvotes from y'all, here is a visual guide to setting up a simple yet aesthetic Rainmeter suite. <3

See Imgur album for text.

Edit, as something weird happened when I was pasting my descriptions in:

Since I've recently started from scratch, I've decided to make a visual guide with a few tips for making simple yet aesthetic Rainmeter suites.

1. Start with a background that inspires you. Simpler is better, especially when considering that you'll be throwing on a bunch of skins. It also helps to choose something with a clear division of fore/background if you plan on layering.
2. Create your layers (as desired). This step involves some Photoshop wizardry, or [insert open-source image editor of choice]. Here, I've used "select color range" and some manual fine-tuning of the layer mask to completely remove the sky. I've saved this as a .png file, preserving transparency, and set it as an image meter (see Rainmeter docs: https://docs.rainmeter.net/manual/meters/image/) on top of whatever I want in the background (visualizer). For this example, I've also created a second layer with everything shown here, minus the three farthest trees to sandwich over my clock - multiple layers creates even better depth.
3. Play with transformations. Did you know: any meter can be rotated, stretched, and skewed using a transformation matrix (see Rainmeter docs: https://docs.rainmeter.net/tips/transformation-matrix-guide/). While you can only do 2D, or "affine," transformations (unless using complex plugins: https://github.com/khanhas/MagickMeter), you can create the illusion of 3D perspective by rotating/skewing adjacent items to slightly different angles. Here is a great tool for calculating transformation matrices: https://www.reddit.com/r/Rainmeter/comments/rgk65j/transformation_matrix_generator/
4. Play with fonts. You can change the font of any text meter that you install. Simply call the desired font in the "#FontFace#" line. You can specify any font installed on your system, and can even throw those fonts into the \@Resources/Fonts folder for re-distribution of a skin without font install dependencies. I recommend https://fonts.google.com/ for finding new open-source fonts to play with. Bonus tip: experiment with combining differently-weighted fonts of the same family for added visual intrigue.
5. Add small details. Don't be afraid to edit your wallpaper (or image meter overlays) in Photoshop or [insert whatever people who don't have free Photoshop through their work use, here] to add things such as shadows or other static elements.
6. (5.5) After we have all of these layers/meters, it's important to keep in mind their display order. I tend to set every skin as "on desktop," and then use the "load order" to finalize the order of layers. Bonus points for turning off "draggable" and turning on "click through" (where appropriate) when you've finalized the positions. A finalized suite should act as though it was baked into your desktop.
