Hello Randi, we like you ideas. In particular entry #4 for its simplicity. Entry #1 and #2 are a bit to complicated but still we like their symmetry. Usually our microarrays are very symmetric and based on simple aligned matrix. Have a look on google (images: microarray). Keep posting and thanks to take part to the contest!
Hi Randi, I like the letters form by circles! ...but I think that the D is not very clear. Do you think it is worthy to write a small "d" instead? Keep uploading!!
