Anyone know of a theme that is similar but not identical?
You might find a few that are "similar" on here - look in wordpress "magazine" section. Good luck
Pocket theme is pretty close
BigFeature is closest thing to Uncrate.com that i've been able to find.
Try Newssetter of themefuse, look very close. Don't know why
The only similarity Newssetter between Newssetter and Uncrate is the site title and menu. Nothing else is similar. The layouts are completely different.
I did not think there you will find 100% same but there many similar item at least 50-70% similar you need to customize it according to your need. Its all about 2-4 hours work may be.
