I tried sticking to the icons you really like , while trying not to directly copy them . The J is a little bigger and tilted to include the slight playful attitude . The Shape behind the black box is a mere visual element and the knockout as well as the gradient can be changed to anything else . The font is Roboto , so there shouldn ' t be any copyright problems arising . The different icons are 1024 px , 512 px , 248 px , 128 px , 48 px , 38 px and 16 px . Link to the sheetIf you have any feedback feel free to get back to me . <| sep |> I think the big problem is people feel like we are subsidizing horse and carriage builders and whip manufactures . One needs money because the product is dying and the other needs money to get off the ground .
