the colors are much better and I like #44, but don't quite understand the blocks around the "T". I agree that spatially that part of the logo needs something, but I'm not sure the blocks are it.
Here i provide couple update Ut combined with leaf :#104 #105 #109 UT: #109 with swoosh : #122 #123 UT in the sphere: 3D #144 #145 #151 flat versions: #155
