Sorry for the delay. Here's some new submission, #23 is a version with no background as you requested. #24 and #25 is using rotation of "90 minutes in a clock" to replace the zero. Also try different font type. Any comment or suggestion are welcomed. Thank you
I have a new idea on #62 - #67. The 0 have multiple meaning, it could be a clock and a man hugging his family in his arm, that represent having more family time. Some of word "minutes" are also changed to a clock theme. Any comments are welcomed. Thank you.
