I spent some time on iMac G4 using Photoshop CS4. I'm surprised by how smooth it is even though I might have about a hundred layers with layer effects on. An absolute joy to work with.
The thing is, I have found
Audion and become a power user; I adore skinnable software. I don't want to have huge libraries of mp3s on my G4, and playing CDs on an actual CD player is far less noisy, but I do enjoy listening to internet radios on it. Audion is great for that and I like how I can have it visible in the bottom corner of the display, next to the dock so I can always see the name of the song that the channel is playing. However, I've noticed that even though the collection of faces (skins) available for it is vast, there's not a lot of them that are visually very well made, would still display the fonts correctly (certain OS9 made themes probably just won't), and also fit to a bottom corner to be dock height. So I started doing some interface mockups to test what I might like; Once I have a few, I'll probably try to create a new Audion face or several, depending on how difficult the phases after the visual design is.
Also, when I listen to radio channels, I often write down the names of great songs so I can look into them and purchase them later. Today after some experimenting, I managed to write an Applescript for Audion that logs the currently playing track to a plain text file, so I don't have to open a text file, manually type it in, and wait for the text to scroll so I could see the whole thing! I have a script like that for iTunes and I was actually quite surprised that by modifying it, I was able to translate it for Audion in 10.5.8. Audion's documentation had no mention of scripting, but I tried adding Audion to Script Editor's library, and that gave me the hints!
Here's my first little mockup, no modern computers were used. Imagine it next to the dock. (Oh! Maybe I should make a Candybar dock with the same wooden texture to match!)
