If you've been doing some digging into Tauchain Agoras, then it's mostly likely that you're already in the Telegram group. But if you're not, and want to weigh in on your favourite logos, you're invited to get into https://t.me/tauchain to vote. Please note that this refers to the logo contest that has just recently concluded. Once you're in the Telegram group, please check the pinned message for the voting procedures on the final set of logos.
To everybody that has submitted - thank you for your participation! The winning designs will be announced in two weeks, before the end of April 2018.
On a personal note:
My favourite logos are the ones submitted by @capitanart here: https://busy.org/@capitanart/we-present-to-you-the-implementation-of-our-proposal. Some thoughts on my picks:-
Why this Tau logo?
I like that it's a cross between a type and a symbol. Moreover, the saturated seapunk colour palette is striking and largely untapped in the cryptocurrency market or anywhere else in general. I've never come across such an edgy blockchain, so it's quite fitting for maximum logo peacocking. It looks fresh.
Why this Agoras logo?
Having a logo that clearly shows "a" instead of Bitcoin's "b", dressed similarly in Bitcoin's gold is somewhat poetic. If the project works, Agoras could end up being the alpha coin of coins. In that case, I'd prefer something strongly simple, symmetrical, and familiar. It's a fitting design space for such an epic coin..
If you've read til this part, you must've noticed that I'm just trying to reason out my preference in logos with some important sounding words. But I hope they made some sense.
My second choice for the same reasons would be @orelmely's logo designs.
If you've actually read through this entire post and don't even know what project I'm talking about here, then check this FAQ on Reddit out, if you're curious. For me, the reading material that made me put some serious time looking into this project was @trafalgar's What Is Tau? - My Only Other Crypto Investment. To be honest, now it's the only blockchain project I'm into other than Steem these days.
