Design Contest 1 : Result
I think the difficulty of this contest was enough to prevent participation. I have 6 entries,displayed in the image below. All of these were very pleasing solves,the winning entry in particular. The names are written exactly as they called themselves in the mail.
Two of them,Bram and Muhorka, used 14 circles.Bram wins, as his submission was earlier.

This is another masyu variation that i developed recently.

Briquet
This is a briquet.I first saw this type at the OAPC. I designed a symmetric layout for this.The opening is easy,but the difficulty rises in the second half.The empty space in the middle did not go wasted. Rules:
Place 2 sets of 6 rectangular slabs of 1x3 size ,without touching,each slab having a different permutation of the numbers 1,2,and 3.One set should be horizontally placed ,and the other vertically.
