T=1hour

This photo was taken at 1hour. The astute among you will notice this is a new vessel altogether. I decided neither of the mugs was acceptable, and found this nice clear glass vase to replace them. I was also able to make him stand up by leaning him against the side of the vase, which also conveniently lets me put a ruler up behind him. It's not quite flush with him, so there's a bit of an angle effect to the measurement, but it should be good enough to measure relative growth of the little guy.
