I kind of like the current logo, so I made a few remakes of it.
Think that's enough different versions of one scene for now.
I'll be working on something new now.

my attempts

simple elegant

   
   

Will animated png be supported?

Example (view with firefox)
   

Edit: Added New Designs.

another logo (darker style i think), and its icons

                   

I tried making a few logos but they burn my eyes so I'll just stick to simple icons.

I included 256 pixel icons since someone mentioned them.

my attempt    

2nd post as attachment sorting was getting a bit annoying in the 1st one. seems to sort things rather random :/

My try.
Hope you like it.

Added some variants.
May be I can improve the curves ?
