First of all, as you might have heard, Andrea Libman is participating in the Ride to Conquer Cancer the next week. Sadly, her team mates haven't met their donation goals yet and will not be allowed to participate if they don't.
Thus there are some auctions to help to raise funds. Two of my pictures are being auctioned off. They will be 16"x12" and signed by the wonderful Andrea Libman.

Read more about it here [link] and check out these and the other auctions here [link]

But that is not all. If you've already heard of Kallisti, then you can start looking forward to the third installment on June 22nd-23rd.
If you have no clue of what it is, it will be a charity 24h livestream event. Half of the funds will go to GalaCon, while the other half will go to Bronies for Good.
There will be a livestream, in which you'll see many artists draw at the same time. What are they going to draw? Why, it will be your requests. (Canon characters sfw requests that is)
And while you can watch several artists draw at the same time (split screen) or go to the one you prefer to watch or watch all of them at the same time, it's up to you really or how many browser windows you can manage^^.
Well, while that is going on, you'll hear a skype chat of the artists or an interview with special guests, like Andrea Libman, Dennis Hu, Amy Keating Roger, M.A. Larson, and more.
We might randomly break out in song. Some actually can sing.
Are you looking forward to it yet?

Read more about it here (and note that it's not finalized, there probably will be more special guests to interview and more artists who will be drawing, among them there might be a certain Mr. JJ ) [link]
