as the title says I'd like to show the content of one sketch in another sketch. I send the pixel array with the built-in network library but the transfer is very slow even with a window size of 200 x 200. Basically I do the following:

Server:

1. Convert pixels array to byte array.
2. Merge all byte arrays.
3. Send byte array to client.

Client:

1. Wait, till there are more ( or as many) pixels as there are in the clients window ( the client's window dimension is the same as the server's window dimension).
2. Convert byte array into seperate byte arrays for each pixel.
3. Convert byte array to int.
4. Set pixel.

Server:  http://pastebin.com/NYaeVuU1

Thanks in advance.
