I saw a similar tee elsewhere, but I like that in this case the proceeds go to OpenSSL.
Also, the fact that a t-shirt can be made out of this supports Patrick McKenzie's article [1] yesterday, commenting on how this bug (or rather, its announcement) has been a case of successful marketing.
OP here. Mandatory disclaimer: we're not affiliated with the OpenSSL Software Foundation but we thought it was a good idea to launch a commemorative Heartbleed t-shirt and donate all proceeds to the foundation.
The Teespring base cost for the t-shirt is around $11, the remaining $4 will be donated to the OpenSSL Software foundation once the campaign ends.
