I confirm I have received the bounty from escrow. Thank you EricKennedy, the LedgerWallet team and redsn0w.
I was trying to make many different styles to make the usb key and logo and none of my methods works on all platforms.
...I will see that this signature indeed works everywhere like it was asked by the OP
It is not a trivial task to make designs compatible to mobile platforms. My approach is first to avoid what I call "rogue" characters. Some morph into unpredictable sizes, some completely vanishes on either mobile platforms. Then, I would design with those character "disabilities" in mind and try to minimise their impact on overall layout.
It is not impossible to achieve, it takes time to reach a compromise. You can test those when the signature campaign commences.
Congrats medUSA you proved again that you are true professional.
Conteaza, you are a
true professional yourself. Your 3D effect and the ribbon design is VERY impressive. You have my utmost respect.
