Unconventional Art Software

[Corrupted Unicorn]

Give me your wackiest software to make art.
By art, I mean any kind of art: visual, written, audio, videos, whatever else you can come up with. 
We're not looking for industry-standard or the most complete software with lots of features: but we're looking for off-kilter, wacky and even fun programs.

Think less Photoshop & Krita, more MSPaint and KidPix 

Free software, browser-ready material and links are appreciated but not necessary.

Keep in mind, some of these are old software that might not be compatible with your current OS.

Here's my list, I hope you add to it!

Drawing/Paint Programs

• MSPaint (online version)
• Kidpix (online version) & Kidpix Deluxe
• Magic Artist Deluxe (Disney's Kidpix, a personal favourite of mine)
• TuxPaint
• MarioPaint...? (hey I heard a certain game dev started with this!)
• Beautiful Doreena (links to video about it)
• Pixilart (for pixel art)
• PiskelApp (for pixel art)

Writing Programs
None so far... add some of your own!
WordArt, simple vector art features and Clippy are the wackiest elements I can think that were on a text editor software. Just to get your gears turning 

Music

• BeepBox
• LMMS (perhaps well-known, but hey it's free!)
• JummBox

Animation

• FlipAnim
• Clipnote Studio
• Microsoft 3D Movie Maker
• Assorted "cartoon movie studio" games (too many to count: Simpsons, Spiderman, Tiny Toons, etc.)
• Pencil2D

Games

• Bitsy
• Twine
• Scratch
• RPG Maker
• Bopimo
• Pocket Platformer
• Adventure Game Studio

3D Modelling

• Vertex Meadow (online tool to create simple 3D worlds!)
• SweetHome3D (for home interiors)

Assorted Other
These can do the "job" of other programs, but maybe they specialize in something that doesn't fit in other categories.

• Electric Zine Maker (for Zines)
• ViperCard
• ASCII Paint
• Talkmodachi - Text-to-speech Tomodachi talk
• Balabolka (text-to-speech. might need you to install voice packs)
• Animated Screensaver Maker
• DVD Styler - to make DVD menus!
• RW-Designer Software - Different programs to make icons, cursors, favicons...

I poured everything I know and comes to mind onto this list. If you want your contributions to be added to it, just tell me along with your forum post! 

Let's give all Melonlanders tools to experiment, play with and make art, of course!

ooh these are all so cool~!

my laptop has KolourPaint on it (a KDE application - like MS Paint but for GNU/Linux) and i use that primarily to make things.
i do have Procreate on my tablet but i don't really like using it much for some reason. i just have it there like i do with Krita on my laptop - i never use it, i just prefer not to use it :P

i mean, Aseprite looks good, but i have no moneyyy!!    plus i make pixel art in KP as well lol
eh, i'd rather just wing it with KolourPaint. MS Paint was good but i can't tolerate Windows anymore at all unfortunately.
also my laptop has GIMP but it's entirely just for removing backgrounds on things.

I've actually created quite a bit of artwork in Microsoft's Paint 3D, which is a shame because it seems they now want the program to go away. It's pretty easy to use and has just enough functionality for me to feel comfortable using it with my very limited 3D modeling skills.

For Music:
Sonic Pi and Supercollider - both are scripting languages that result in sound. Sonic Pi is rather simple, and was developed for the Rasberry Pi - getting it to run on x64 systems ain't that easy. SuperCollider is much more complex and powerful. Both are free software.

Many years ago, I made pictures with Project Dogwaffle. People who enjoy a retro experience might like this!

Also, while Blender is not exactly obscure, many people might not know about the 2D-Animation and the sculpting mode.

Shameless self-plug: Use the turtle if you want to pixelate anything!
