I've updated the info for the youtube videos to explain the licensing situation for Sorlo, hopefully this is okay:

Oh right that's a good thought, so seems I can include Sorlo in an extra package of sprites users can download to add to Bounce Metronome. 

The original reason for making it a separate package was just to reduce the download size, I have to count the KB for the installer or it can get very large easily.

That's okay, yes will do that. I had a couple of others from here that were CC-By which I might include later in an optional "add on" with extra sprites to try out.

For this next release I've used some public domain sprites from for now, (some bird sprites and musical instruments, flowers, umbrella, look nice bouncing). This is the default I'm using now instead of Sorlo, it's also nice, kind of fun for users:

The sorlo one goes really well with the animation so it's nice to use it for the youtube videos which I think is permitted with the share alike so long as I make the video itself under the same license, is that okay? 

Also though I can't include it myself with the program, I wonder if it is okay to point to this url for users of the software as a place where they can download extra sprites to use with the software including sorlo?

It's great to have this resource for developers like myself who can't afford to employ graphic artists to do their graphics - I just don't have the necesary skills to draw decent character sprites myself.

Just checked the FAQ for this site, missed that somehow before, I see it does mean I have to release the source code which I can't do so, so I won't be including it in the installer. Sorry for the mistake.

Just realised, perhaps one could argue that the software itself is a derivative work if it includes the sprite in the installer? I'm not sure how that's interpreted in this situation.

So - just in case, it might be safer to keep to public domain sprites in the installer for the software.

I think there is no problem using share alike sprites in the demo videos of the software because then it's clear that the demo video is the derivative work and I have no problem releasing all videos including your sprite under the same license as the sprite itself. 

For a bit more background, the thing is that normally the software just displays bouncing balls, or bouncing numbers or the like, but there's an option to select a sprite in the place of the bouncing balls (a minor option in the software). The user then can browse to choose any image they have to use as a sprite, but I wanted to include a few in the installer as demonstrations so they can use the feature straight away.

Are you okay with me using your sprite in the demo videos for the software? (if you prefer not for any reason I will take them down).

@doudoulolita  glad you like the animations and the way I used your animation. Sorry I can't do it as open source as I'm doing this as a small sole trader business, I have no other job.

I'm using it under the creative commons atribution share alike license which is the first of your three licenses - which permits commercial use so long as I attribute it correctly - and also share any changes I make to the image. It doesn't require me to release the source code of the project that uses the image, just release any changes to the image itself.

 You are free:

  • to Remix — to adapt the work
  • to make commercial use of the work

Under the following conditions:

  • Attribution — You must attribute the work in the manner specified by the author or licensor (but not in any way that suggests that they endorse you or your use of the work).


  • Share Alike — If you alter, transform, or build upon this work, you may distribute the resulting work only under the same or similar license to this one. 


However from what you say maybe you didn't understand those implications of the license when you applied it to your work? If so, will respect your wishes whatever they are.

I haven't yet released the new version of Bounce Metronome with your sprite in it, will do so soon. Will leave it out for now until I hear from you whether it is okay to include it or not.

I like your sorcerer, think it's great, and have used it for my Bounce Metronome Pro as an example to show users how they can add a sprite for the bouncing balls.

Youtube video here:

And in a 3D scene:

It uses various bounce animations to help musicians keep good time for music practise.

Those videos are of the beta and I'm planning to include it in the release as an example when it's ready - with attiribution of course as per the license.

You are welcome to a complementary llicense for the program in appreciation :)
